水工建筑物地基的渗透计算

Calculation of infiltration for foundation of hydraulic structure

位于有限深度透水地基上的档水和壅水建筑物，需要进行地基的渗透计算，以确定地基的渗流量及其渗透稳定性。通过理论分析，提出了计算地基的渗流量、渗透水力坡降和渗透流速、以及建筑物底面的渗透压力和扬压力的简捷方法，该方法有足够的实用精度。

Retaining and retenting works need to calculate infiltration of foundation in order to concIude the seepage quantity and steady quality abOut seepage, which lies in the foundation infiltrated with limited depth. Simple way on how to calculate the foundation of seepage quantity and hydraulic slope of seepage have been brought up by theoretical analysis, including seepage velocity and seepage pressure of the bottom of works and seepage uplift. The equation has enough accuracy.
