摘要
利用渗流的基本理论 ,分析了武汉软土地区的基坑降水工程 ,总结了不同围护结构及降水方案的地下水渗流特征 ,提出了按渗流特征计算坑外由于降水引起附加沉降的简单方法 .
Based on the basic theory of seepage, the analysis of the precipitation project of foundation in clay area in Wu Han is made. The characteristics of seepage are then discussed considering circumstances of timbering and ways of lowering groundwater. The evaluating formula for additional subsidence induced by the lowering groundwater is presented in this paper and comparison is made with a practical case.
