摘要:

通过计算水泥土挡土墙周围的渗流场，研究了墙侧水压力的变化规律.结果表明：水压力系数沿高程并非常数，且受到墙侧土层分布及其相对透水性、墙基土的透水性和下卧不透水层埋深等因素的严重影响.总体来说，考虑渗流时墙后的侧压力总小于不考虑渗流时的相应值，且当墙前的被动土压力系数较小时，考虑渗流时该侧的侧压力则大于不考虑渗流时的相应值，因此，这种情况有利于挡土墙的稳定.

Abstract:

By calculating the seepage field around the cement-soil retaining wall, the variation law of water pressure on the wall side was studied. The results show that the water pressure coefficient is not constant along the elevation, and is seriously affected by the distribution of soil layer on the wall side and its relative permeability, the permeability of the wall foundation soil and the buried depth of the impervious layer lying down. In general, the side pressure behind the wall when considering seepage is always less than the corresponding value when seepage is not considered, and when the passive earth pressure coefficient in front of the wall is small, the side pressure on this side when considering seepage is greater than the corresponding value when seepage is not considered, so this situation is conducive to the stability of the retaining wall.
