It is suggested that the impervious wall combined with curtain grouting should be taken as the main vertical impervious body for seepage control, and that the full use of slope wash and fully weathered zone as horizontal impervious blanket should be taken to reduce work load for seepage control
建議採取截滲墻結合帷幕灌漿作垂直防滲體為主的防滲措施，同時充分利用坡積土和全風化帶作為水平防滲鋪蓋以減少防滲處理工作量。 -
The condition of water pressure acting on the both sides of cement - soil retaining wall is researched by computing the seepage field around the wall. it is illustrated that the coefficient of water pressure, which isn ' t constant along the height, is affected seriously by some factors, e. g., the distribution and relative hydraulic permeability of the soil beside the wall, the hydraulic permeability of its foundation, and the buried depth of the impervious layer. as a whole, the lateral pressure acting on the wall based on seepage is always smaller than that without regard to seepage in the non - excavated zone. moreover, the pressure based on seepage is greater than that without regard to seepage in the excavated zone if the coefficient of passive pressure is smaller than 1. 176. this case is of great advantage to the stability of the wall
通過計算水泥土擋土墻周圍的滲流場，研究了墻側水壓力的變化規律.結果表明：水壓力系數沿高程並非常數，且受到墻側土層分佈及其相對透水性、墻基土的透水性和下臥不透水層埋深等因素的嚴重影響.總體來說，考慮滲流時墻后的側壓力總小於不考慮滲流時的相應值，且當墻前的被動土壓力系數較小時，考慮滲流時該側的側壓力則大於不考慮滲流時的相應值，因此，這種情況有利於擋土墻的穩定
