地铁车站深基坑涌水量预测分析

Prediction and Analysis of Water Inflow in Deep Foundation Pit of Subway Station

地铁车站深基坑涌水量关系到基坑支护形式的选择、开挖施工作业方式及抽水井的数量等,所以,地铁车站深基坑涌水量的预测在地铁车站基坑设计及施工中有重要作用。论文根据现行规范采用多种计算模型进行车站基坑的涌水量计算,并将计算结果进行对比分析,探索各模型的优缺点,以指导设计及施工。

Water inflow from deep foundation pit of subway station is related to the selection of support structure,excavation construction mode and the number of pumping wells.So,the prediction of water inflow from deep foundation pit of metro station plays an important role in the design and construction of foundation pit of Metro station.According to the current specifications,this paper uses a variety of calculation models to calculate the water inflow of the station foundation pit,compares and analyzes the calculation results,and explores the advantages and disadvantages of each model to guide the design and construction.
