    2 ）耕作制下紫色土的產流主要機制是： 1 ）當雨前土壤含水量未達到飽和狀態時，表面產流起始時間有明顯滯后現象，這與紫色土的快吸水性和較多非毛管孔隙密切相關；當雨前土壤較乾燥，降雨初期雨強較大時，易形成臨時相對不透水表層，表面產流峰也有明顯滯后現象。 2 ）表面徑流的產流方式主要是超滲產流，當土壤達到飽和狀態后，有四川大學博士學位論文小部分回歸流發生，但主要是飽和超滲產流發生，因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產流，與降雨過程有明顯的滯后，而且雨停后的壤中流產流歷時與降雨特徵無關。

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
