关于土坝渗流,工程上一般要求解决下列问题:一是浸润线的位置,其目的在于确定逸出点的位置;二是渗透流速和渗流量;三是逸出段长度。浸润线的位置,直接影响逸出段长度;渗流量的大小又影响土坝的蓄水功能。土坝渗流是从逸出点经逸出段下渗的,日久会冲刷下游逸出段坝面,危及土坝的安全,同样 On earth dam seepage, the project generally required to solve the following problems: First, the location of the infiltration line, whose purpose is to determine the location of the escape point; the second is the infiltration velocity and seepage flow; the third is the escape length. The location of the infiltration line directly affects the length of escape section; the size of seepage affects the storage function of earth dam. Earth dam seepage from the escape point through the escape section of the infiltration, the long run will escape downstream dam section, endanger the safety of earth dam, the same
