武汉某深基坑工程监测分析

Monitoring and Analysis on a Deep Foundation Pit Engineering in Wuhan

简要介绍了武汉某深基坑的围护设计、施工和监测方案,并对主要监测结果进行了详细分析,并得出了一些有利于基坑安全的指导性的结论。监测结果表明:地下连续墙后的堆载将对墙体的变形产生很大的影响,施工中,要将开挖土方及时运出场外,确保基坑及相邻建筑物的安全。由于基坑施工周期较长,温度的变化对监测结果也有较大的影响。

The supporting design,construction and monitoring schemes of a deep foundation pit in Wuhan are introduced here in detail,and the main monitoring results are analyzed in order to get some instructive conclusions that could ensure the security of the pit.The monitoring results indicate that the preloading behind concrete diaphragm wall would have great impacts on the deformation of the concrete diaphragm wall.So during the construction of the pit,the excavated earth should be transported out in time in order to ensure the security of the pit and the adjacent buildings.Moreover,due to the long period of foundation pit＇s construction,the seasonal variations of temperature would have great impacts on the result of monitoring.
