CANLEX Blasting Experiment Summer 1997

9727328查理这一行动是为了支持科罗拉多州立大学的韦恩·查理教授参加加拿大液化实验。许多大型建筑，如水电大坝和尾矿坝，要么建在沙堆上，要么部分用沙子建造。如果沙子松散并快速加载，那么沙子的结构可能会坍塌，土壤可能会液化，可能会失去大量的强度。一项主要的研究工作正在进行中，以研究松散的无粘性土壤的行为。这项研究的大部分是名为加拿大液化实验(CANLEX)的大型合作研究项目的一部分。该项目由艾伯塔大学与拉瓦尔大学、卡尔顿大学和不列颠哥伦比亚省大学合作控制和管理，并得到辛克鲁德大学、森科尔大学、不列颠哥伦比亚省海德鲁大学、魁北克海德鲁大学、肯纳科特大学和高地谷铜业公司的工业支持。目前的研究包括研究松散砂土的力学和地球物理性质，以及开发合适的本构模型。研究还包括对大型垃圾场中发现的矿山废物的研究。查理教授正在协助这一项目的当前阶段，即对艾伯塔省辛克鲁德遗址进行爆炸加载，试图模拟地震循环加载。目的是在饱和松散沙的沉积物中产生足够的孔压，使场地液化。这是查理教授有相当丰富经验的领域。

9727328 Charlie This action is to support the participation of Prof. Wayne Charlie, Colorado State University, in CANLEX -- the Canadian Liquefaction Experiment. Many large structures, such as hydroelectric dams and tailings dams, are either built on sand deposits, or are partially constructed with sand. If the sand is loose and is loaded rapidly, then the structure of the sand can collapse, the soil can liquefy and a large amount of strength can be lost. A major research effort is underway to study the behavior of loose cohesionless soils. Much of this research is part of a large collaborative research project called the Canadian Liquefaction Experiment (CANLEX). This project is controlled and managed at the University of Alberta in collaboration with the Universities of Laval, Carleton and British Columbia and with industrial support from Syncrude, Suncor, B.C. Hydro, Quebec Hydro, Kennecott and Highland Valley Copper. Current research includes the study of the mechanical and geophysical properties of loose sands and the development of appropriate constitutive models. Research also includes the study of mine waste materials found in large waste dumps. Prof. Charlie is assisting in the current phase of this project, namely to subject the Syncrude site in Alberta to blast loading in an attempt to simulate earthquake cycling loading. The objective is to generate pore pressures in the deposit of saturated loose sand sufficient to cause the site to liquefy. This is an area in which Prof. Charlie has had considerable experience.
