TopicGeosynthetics for Soil Reinforcing
Abstract Because geosynthetics are a relatively new class of nontraditional civil engineering materials, the presentation briefly...
  introduces the types, functions, applications, and properties of geosynthetics. Then the use of geosynthetics for soil reinforcement is discussed in some detail, with specific applications to embankments on soft foundations, steep slopes, and the backfills of retaining walls and abutments. Emphasis is on the material properties of the geosynthetics required for design and construction. Results of recent research activities in these areas are also mentioned.

Topic Use of Laboratory and Field Techniques with Unsaturated Flow Modelling to Assess Coarse Grained Material Behaviour: Application to Waste Rock Piles
Abstract Mining activities produce large volumes of waste rock, which are typically deposited in piles on the soil surface, above the water...
  table. Such piles can cover areas of several tens of hectares and can reach over a hundred meters in height. For hard rock mines, the waste rock grain size can vary from silty particles to metre-scale blocks. The internal structure of a pile constructed on a relatively flat surface typically includes two main zones. The first zone corresponds to the heart of the pile, and is formed by several sub-horizontal stratifications (with dense and loose layers) due to the heavy mine equipment traffic which induces local compaction and degradation of the waste rock. The second zone corresponds to regions where waste rocks are deposited by push-dumping or end-dumping close to the external flank of the pile, inducing grain size segregation along the slope. Depending on the deposition sequence, grain size distribution and bench height, a gradation may then be observed, with coarser particles (with cobbles and blocks) near the base and finer particles (silty sand and gravel) near the crest, together with inclined stratifications. These internal features affect the distribution and flow of water (and air) in the pile.
To assess the internal distribution of materials within the pile, a combination of several tools is usually required which can provide information on the hydrogeological and geochemical characteristics of the waste rock. In this regard, geophysical tools (particularly EM & GPR) are very interesting because they can lead to a three-dimensional mapping of property variations. The information gathered from a combination of appropriately selected techniques can be used to construct numerical models to further study unsaturated water flow and reactive transport. Such simulations help better understand the pile response in its actual and future states, which in turn provides input to adjust the deposition sequence, to plan for closure, and to select an in situ groundwater monitoring strategy.
The presentation will give an overview of techniques that have been developed to characterise material properties in the laboratory and in the field, and to obtain a general picture of a pile’s internal structure. Additional results on unsaturated reactive transport modelling, obtained by the lecturer and collaborators, will also be shown to illustrate how the internal pile structure may influence its hydro-geochemical and environmental response.

TopicGE5 (Glenmore Trail, Elbow Drive and 5th Street) Retaining Walls
Abstract The GE5 (Glenmore, Elbow Drive and 5th Street) Project is a recently completed $110 million intersection and road improvement...
  project for the SW of Calgary, designed to improve traffic flow on two major arteries. This project includes roadworks for the interchanges at Elbow Drive and 5 Street S.W., lowering Glenmore Trail 10 m and widening it from four to six lanes, building a new pedestrian bridge over Glenmore Trail, and incorporating public art along Glenmore Trail as part of The City of Calgary's Public Art Program. Mechanically Stabilized Earth (MSE) retaining walls with a total face area of 16,000 m2 were constructed along the north and south sides of the project in order to facilitate the required grade separation. Nilex was part of the project delivery team, and provided design, construction materials and construction support for the concrete-faced mechanically stabilized earth walls that form a major component of the construction work. Jason will talk about some of the design and construction challenges encountered including highly variable foundation soils, restricted construction access, and winter construction.

TopicFoundation Design and Test Results for the New International Airport in Bangkok, Thailand
Abstract The Suvarnabhhumi airport, the new international airport in Bangkok, Thailand, covers an area of 8 km by 4 km (8,000 acres)...
  in a former swamp, a flat marine delta about 30 km south of Bangkok. The soil profile consists of a thin weathered crust on typical soft to stiff, compressible Bangkok clay deposited on a sand layer at a depth of about 25 m extending to about 47 m. Below the sand lies an about 10 m thick layer of hard silty clay followed by very dense sand to great depth.
Most of the area is devoted to runways, roadways, and parking, which required extensive ground improvement to minimize settlement. The structures consist of several units sharing footprints: terminal building, concourse, trellis structure, parking garage, and elevated roadways, which are founded on three types of piles installed to the sand below the clay layer, 1,000mm bored pile, 600mm diameter bored piles, and 600mm driven cylinder piles. A total of 25,000+ piles were installed. The stress-bulbs from the various foundations overlap, resulting in a complicated settlement analysis. The design of the airport started in 1995 and construction was completed in 2005 at a total cost of close to US$30 billion.
The lecture will present aspects of the soil improvement work, analysis of results from pile tests, and the design of the piled foundations for capacity, settlement, and downdrag.

TopicKicking Horse Canyon Project: The Trans Canada Highway's Great Challenge
Abstract Until the 1950's, the Trans Canada Highway east of Golden to Yoho National Park was little more than a trail. During the...
  post-war highway expansion, the route was upgraded to a two lane paved road. With the exception of lane additions at two locations, little upgrading work was done until 2002. Completing the four-laning of this 26 km section of the TCH is high on the BC Ministry of Transportation priority list as it forms part of the Pacific Gateway strategy. The work is being carried out in a number of stages as funding permits. Recent work has included the very successful $130M Park Bridge section, which opened before Labour Day, after only 22 months of design and construction under a DBFO procurement process.
The presentation will focus on geotechnical issues encountered on this project and on previous completed works. Of the four remaining stages, the 5 km Canyon section will provide the greatest challenge because of the steep terrain, natural hazards and geotechnical concerns. At an approximate capital cost of $500M, it will be among the most expensive sections of the highway on a kilometre basis in the province. Numerous options are being considered, including a long (2.9 km) twin bore tunnel and surface routes with multiple structures and protection works. These will be discussed from a mainly geotechnical perspective.

Topic Topic 1 – Statnamic Load Testing: Update on Recent Activities Worldwide
Topic 2 – Intelligent Pile Driving with a Diesel Hammer
Abstract Topic 1 – Statnamic load testing: update on recent activities worldwide Statnamic load testing is a relatively new method of...
  performing foundation load tests. The method uses high-pressure gas to generate large forces using a small amount of reaction mass. As the name implies, the duration of the applied load is longer than that of a dynamic load test (impact load) yet shorter than a static load test. The advantage of the Statnamic load testing method is its ability to mobilize the foundation as a rigid body, rather than introducing stress waves as with dynamic load testing. Statnamic testing can be performed on any type of foundation element, including footings, plates, driven piles, drilled shafts (caissons), augercast piles, expanded base piles, barrettes, and pile groups. The method can be used on batter piles, and has recently become popular as a lateral load testing method to simulate seismic and ship impact loads. This discussion will give listeners an update on recent Statnamic activities around the world, including new developments in the equipment and improvements in pile instrumentation and data interpretation.
Topic 2 – Intelligent Pile Driving with a Diesel Hammer
This talk will describe the technology behind the development of an automated energy control system for a diesel pile hammer. An adjustable hammer throttle and feedback from an energy monitoring system was used to create a fully automated diesel hammer - now patented. The performance of this system is described in reference to a piling project in Canada where this automated energy control system was used to obtain an unprecedented level of quality control and assurance – data and graphs from the project are presented. The hammer energy control system (ECS) was used to successfully control and maintain a prescribed impact energy for the diesel hammer even as the soil resistance changed. Future applications of this system will also be discussed; such as automatic hammer energy control based on allowable sound levels, allowable vibration levels, and pile stresses.
