摘要
结合某水利枢纽基坑工程,采用弹塑性有限单元法分析基坑工程在不同设计方案条件下,支护条件和开挖降水对周围地面沉降及建筑物的影响;分析基坑底部位移分布以及不同方案下的支护结构的特性变化,并根据计算分析结果,针对可能出现的问题,提出相应的处理措施。
With one hydraulic junction foundation pit, a finite element elastoplastic method is used to analyze ground and building settlements, change of displacement and supporting induced by supporting, excavation and precipitation of foundation pit. Based on the results, the corresponding measures are proposed for the potential problems.
