深基坑工程监测分析方法

在深基坑的开挖过程中,对基坑支护结构、基坑周围的土体和相邻的构筑物及周边环境进行综合、系统的监测分析,才能对工程情况有深入的了解,确保工程顺利进行.结合立丰购物广场基坑监测的工程实际,针对围护结构的水平位移、地表和地下管线及建筑物沉降、建筑物裂缝的开展情况、地下水位和基坑环境等进行了监测,并依据监测数据对该工程做出了安全性评价.指出了深基坑工程监测中需注意的两个问题并提出了改进意见.

Measurement and Analysis of Deep Foundation Pit

During deep exavation,systematic measurement and analysis of support structure,soil body,adijacent buildings and surrounding environment are necessary to be investigated for the construction situation and the progress.For the deep foundation pit of Lifeng international shopping square,the horizontal displacement of support stucture,the settlement of earth surface,underground pipeline and buildings,the development of building crack,underground water level and pit environment are all measured and monitored.Then the safety of the construction is estimated according to the acquired data.The improvement for two problems of measurment and monitor in deep foundation pit has been proposed.
