在分析水文地质条件的基础上,建立模拟区水文地质概念模型,运用Visual Modflow软件进行数值模型建模,模拟计算了多种典型条件下不同承压排水方案的船坞基坑底部渗流场特征及渗流量,最终给出较为符合实际情况的基坑涌水量;探讨基坑排水装置的设置方案;并指出涌水量模拟过程中应注意的问题。 Based on the analysis of hydrogeological conditions, a conceptual model of hydrogeology in the simulation area was established and the numerical model was established by using Visual Modflow software. The seepage field at the bottom of the dock under different pressure drainage schemes was simulated and calculated The discharge of foundation pit which is more accordant with the actual situation is given finally. The setting scheme of foundation pit drainage device is discussed. And the problems that should be noticed in the process of gushing water simulation are pointed out.
