Examples
- Our site inspection near shek mum kap at the midstream section of the tung chung stream on 14 august 2006 revealed significant sediment runoff from upstream water . virtually no fish and insects were observed in the stream
本会于2006年8月14日在邻近东涌河中游段的石门甲进行实地考察时，发现大量沉积物从上游冲刷而下，本会职员更几乎未能在该河段中找到鱼类和昆虫。 - Firstly , the displacement , stress , strain fields and the working state of dam body and foundation are evaluated by fem . by overloading the upstream water level and reducing rock strength parameters , the failure process of dam foundation is simulated and the failure mode and paths are determined . the results show that when overload method is used , damaged area develops from up - stream to down stream with failure front stays near the interface between dam body and bedrock
首先采用非线性有限单元法对坝体及坝基在不同荷载工况下的变位、应力应变状态展开分析，评价各工况下坝基的运行状态，而后采用超载法和综合法对大坝稳定性进行分析，模拟坝基的渐进性破坏过程，追踪岩体破坏状态的发展演变过程，从而得到坝基在超载和强度下降过程中的破坏模式和破坏发展路径。 - According to the geological conditions of baise project , erosive bands and joint fissures , f6 fault and grout curtain are fully simulated to establish 3d numerical model of the dam and its foundation . 3d non - linear fem is used to analyze the stress and strain and to appraise the operation state of both the dam and it ' s foundation under different operation conditions . by overloading the upstream water level and reducing rock strength parameter , the dam foundation ' s degradation process is simulated and the damage pattern and paths are determined , and finally the safety factor is determined
2 、根据百色的地形地质条件，充分模拟了蚀变带、节理裂隙、 f6断层、灌浆帷幕等，较为真实地建立了坝体与地基相互作用的整体三维数值模型；采用有限元法对坝体及坝基在不同工况下的应力应变状态开展分析，评价各工况下坝基的运行状态；而后采用超载法和综合法对大坝稳定性进行分析，模拟坝基的渐进性破坏过程，从而得到坝基在超载和强度下降过程中的破坏模式和破坏发展路径，最终确定坝基超载安全系数和综合安全系数。
