三维渗流模拟分析场地水文地质参数

3D Seepage Simulation Analysis of Site Hydrogeological Parameters

对于高水位区域的深基坑施工而言,场地水文地质参数的确定、降水方法的选择直接关系到基坑降水成功与否。主要以海运大厦工程为例,在坑外通过抽水试验得到场地水文地质参数,在此基础上通过三维渗流模拟预测基坑施工中水位变化情况,以此为基础采取相应措施确保基坑顺利施工。

For the construction of deep foundation pits in high water level areas,the determination of site hydrogeological parameters and the selection of precipitation methods are directly related to the success of foundation pit precipitation.Taking the marine building project as an example,the hydrogeological parameters of the site are obtained through pumping tests outside the pit.Based on this,3D seepage simulation is used to predict the water level changes in the foundation pit construction.Based on this,corresponding measures are taken to ensure the smooth construction of the foundation pit.
