相邻基坑影响下基坑施工对临近地铁影响分析

摘要

The paper adopts the three-dimension finite element model,undertakes the numeric simulation and calculation of the excavation process of some surrounding subway deep foundation pits,adjusts the overall model by extracting the supervision documents of the side subway of some neighboring subways,and points out the respective promotion and protection measures according to the calculation results.%采用三维有限元模型，对某临近地铁深基坑的开挖过程进行数值模拟计算，通过提取该相邻基坑侧地铁的监测资料，校核调整了整体模型参数，并根据计算结果，提出了相应的加强和保护措施。
