深基坑支护对紧邻建筑物变形的分析与监测对比研究

A contrastive study:analysis and monitor on deep foundation supporting structures to deformation of adjacent building

将深基坑、支护结构及周边建筑物作为一个体系,运用数值模拟分析方法对紧邻建筑物的沉降变形随基坑开挖深度的变化进行计算模拟,与实际监测数据进行对比分析,其结论不但证明了支护方案的可行性,同时也对深基坑工程的安全施工提供了一定的指导作用。

In this paper, the deep foundation pit, the supporting structures and the peripheral buildings are put into one system. A numerical simulation on the settlement and deformation of the adjacent building is processed in term of the depth of excavation. Contrasting the simulation result with the result that monitored on the spot during the construction, the conclusion is made. It proves that the designed scheme of supporting for the foundation pit is feasible. At the same time, it also gives a direction for safety of the consstruction of deep foundation excavation engineering.
