数值法在基坑降水中的应用

摘要

Take a foundation pit dewatering project in Anhui province for example, through the selection of dewatering scheme, hydrogeological parameters of selection area, and used the present mature groundwater numerical simulation software VisualModflow made foundation pit dewatering numerical simulation to the study area, and used the numerical method to establish model for the prediction of water inflow and the effect range after foundation pit dewatering, provided theoretical guidance for foundation pit dewatering scheme optimization and dewatering construction and operations.%以安徽省某基坑降水工程为实例，通过选择降水方案，选取水文地质参数，并运用目前较为成熟的地下水数值模拟软件VisualModflow对研究区进行了基坑降水数值模拟，并利用数值法建立模型预测涌水量与基坑降水后的影响范围，为基坑降水方案优化及降水施工作业提供了理论指导。
