合肥地铁明光路站深基坑监测分析

Monitoring Analysis of Deep Foundation Pit of Hefei Mingguang Subway Station

本文通过对合肥市明光路地铁车站深基坑开挖过程中的深层水平位移、地表沉降和地下水位变化等监测数据进行分析,得出了一些具有价值的结论并给出相应的监测建议。监测数据表明地铁车站地下连续墙的深层水平位移可在一定程度上影响地表沉降,同时地表沉降受地下水位变化的影响,所以在施工监测过程中需密切关注地下水位变化。因此,在施工监测工作中应注意各监测项目之间协同变化作用,考虑不同监测项目之间内在联系。

This paper has gained some valuable conclusions and puts forward the corresponding monitoring advice by analyzing the monitoring data of deep horizontal displacement, surface subsidence and groundwater level changes in the process of deep foundation pit excavation of bright road in Hefei. Monitoring date show that deep horizontal displacement of underground continuous wall in subway station can impact surface Subsidence- to Some extent and Surface subsidence is inlfuenced by the change of groundwater level , therefore we need to pay close attention to the change of the groundwater level in the construction monitoring process. Meanwhile, we should pay attention to the synergy between the monitoring projects, considering the inherent link between different monitoring projects in the construction monitoring work.
