复杂条件下深基坑变形监测分析

摘要

以沈阳北站人防工程深基坑工程为研究对象，基于基坑稳定性及周围土体变形理论，通过对基坑开挖过程进行系统的动态监测和实测数据分析，开展复杂条件下深基坑变形监测研究，以期得到围护桩的最大水平位移和地表最终沉降量等参数，为今后复杂条件下的深基坑工程提供可靠的理论依据。%Taking the deep foundation pits at the air-raid shelters of Shenyang North Station as the research object,the paper undertakes the sys-tematic inspection and real data analysis in the foundation pit excavation based on the stability of the foundation pit and the surrounding soil body deformation theories,and undertakes the research on the deformation inspection of the deep foundation pit in complicated condition,so as to a-chieve the maximal horizontal displacement and surface settlement of the enclosure pile and provide the reliable reference for the deep foundation pit projects in complicated conditions.
