摘要
To analyze stability of the landslide or the slope with relatively weak and gradient side or with water pressure on the gradient outside of its ends,using general methods of slices is fitter than using methods of vertical slices.The method of simplified calculation of seepage flow action is researched in the paper.The calculation formula of seepage force of a soil slice is put out.and then the method of its round pore water pressures is put out on the basis of connection of between face forces and body forces of water.Using those methods as the current calculation formula of the seepage force and the method of the round pore water pressures according to water depth and evidently advanses the rationality of the result.
