摘要
通过对三维非稳定流问题的理论分析,建立三维渗流的有限差分模型,使用地下水渗流软件VisualMODFLOW,并以西安地铁一号线通化门车站深基坑降水工程为例进行计算。将有无悬挂式帷幕两种工况的水头降深计算结果与实际存在悬挂式止水帷幕的实测值进行对比,定量说明悬挂式止水帷幕对基坑降水的影响。
Through to the three dimensional unsteady flow question＇s theoretical analysis, establishes the three dimensional transfusion the finite difference model, use ground water transfusion software Visual MODFLOW, and carries on the computation that take a Xi＇an subway line Tonghua gate station deep hole excavated for building foundation precipitation project as the example. Counted two drawdown conditions of hanging curtain and without curtain, compared to the actual existence of pensile measuaed curtain, the quota showed that the hanging stops the water curtain to the hole excavated for building foundation precipitation~ influence.
