摘　　要：当有渗流产生时,求解水土压力比在静水条件下要复杂。渗透力和重力都是体积力,两者量纲相同,渗透力作用方向与水流方向一致。在稳定渗流条件下将渗透力拟重力化,其物理含义没有改变,与重力叠加后计算水土压力,能简化水土压力计算。其思路清晰、计算方便,在计算挡土结构水土压力工程实践中具有应用价值。When seepage occurs,the calculation of the water and soil pressure is more complex than under static water conditions.Both osmotic force and gravity are volumetric forces,with the same dimensions,and the direction of action of osmotic force is consistent with the direction of water flow.Under stable seepage conditions,the physical meaning of the pseudo gravity transformation of seepage force remains unchanged.After superposition with gravity,the calculation of soil and water pressure can be simplified.Clear and convenient,the calculation method has certain application value in engineering practice of calculating soil and water pressure in retaining structures.
