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。
Combined with the foundation pit engineering of a water project, the finite element method of elasto-plastic analysis is used to analyze the influence of supporting conditions and excavation precipitation on surrounding ground subsidence and buildings under different design schemes; According to the calculation and analysis results, the corresponding treatment measures are put forward according to the possible problems.
