项目摘要
Countries around the world rely on various geotechnical infrastructure for flood control, water storage and hydroelectric power generation. These critical geosystems typically involve a porous media interacting with structural elements such as spillway walls, conduits associated with outlet works or adjoining gravity structures supporting the embankment. The failure of levees, or embankment dams by internal erosion may occur under high water levels during flood events or under normal operating conditions without an apparent triggering event. The latter can be attributed to various factors including decay of existing tree roots or invasive wildlife activities that result in local voids within levees or embankment dams that remain concealed until the safety of the earth structure is jeopardized. The worldwide average cost of failed or damaged earthen structures due to these factors exceeds billions of dollars per year. The negative impact of soil deterioration and erosion-related failure in geosystems is not limited to earth structures. Leaking pipes under or near existing structures are also known to cause sudden and unnoticed failure.
世界各国依靠各种岩土工程基础设施进行防洪、蓄水和水力发电。这些关键地质系统通常涉及多孔介质与结构元件相互作用,例如溢洪道壁、与出口工程相关的管道或支撑堤坝的相邻重力结构。在洪水事件期间的高水位下或在没有明显触发事件的正常运行条件下,可能会发生堤坝或堤坝内部侵蚀的失效。后者可归因于各种因素,包括现有树根的腐烂或入侵的野生动物活动,导致堤坝或堤坝内的局部空隙,这些空隙一直隐藏着,直到地球结构的安全受到威胁。由于这些因素导致的土结构失效或损坏的全球平均成本每年超过数十亿美元。土壤退化和地质系统中与侵蚀有关的破坏的负面影响不仅限于地球结构。在现有结构下面或附近的泄漏管道也已知会导致突然和未被注意的故障。
