深基坑开挖对周边地表沉降影响因素分析

Analyses of Influence Factors on Ground Settlement During Excavation

随着基坑工程的发展,基坑开挖对周边环境的影响越来越受到人们的重视,通过对杭州地铁地表沉降的监测分析,探讨了基坑开挖过程中的坑外地表沉降的影响因素及其规律,并对施工过程中的渗漏事故引起的地表沉降进行了分析,评价了支护结构的科学性和合理性,可供类似工程参考。

With the development of foundation engineering, the influences to the ambience out of the excavation of deep foundation pits have been paid more and more attention. The paper disscusses the influential factors and regularities of ground settlement outside of foundation pit through the analysis to the monitoring data of Hangzhou metro. In addition, the ground settlement caused by leakage was also analysed. Then the scientificity and rationality of the support structure were comprehensively evaluated . It can be available for use in similar engineering.
