Seepage Control Calculation Model And Relevant Problem Of Earth-rock Dam On Infinite Deep Pervious Foundation

Earth-rock dam has advantages of lower requirement to terrain conditions and construction according to circumstances permission, therefore, more and more scientists are engaged in researching it. The seepage stabilitsation of the dam foundation is one of the key problem that influences the earth-rock dam safety. Therefore seepage problem of earth-rock dam arouses focus of the dam engineering field attation increasingly. The earth-rock dam is the main part of the our country's reservoir dam. The existing Seepage control theories to infinite deep pervious foundation are not maturity and perfect.At discussing the seepage control on infinite deep pervious foundation, This paper makes use of the BEM on discussing the seepage control of dam foundation, and build up mathematics model.The difficult of zhe problem arise the part of boundary zone to simulate with difficulty, while solving Vertical seepage control problem. According to basic principle of boundary element method, this paper proposed that we can find out one boundary zone under the diaphragm wall. When solved from that boundary the unknown data is opposite smaller, it can think the boundary suppose to be its real boundary, and makes the model. In the meantime we will discuss the influence of impervious blanket's length for earth-rock's seepage on infinite deep pervious foundation.
