以有效应力原理以及朗肯土压力理论为基础,分析了侧向水土压力计算的问题。孔隙水压力的计算和土体强度指标的取值对水土压力的计算结果影响很大。基于孔隙水压力的分类建议,给出了几种不同孔隙水压力情况下侧向水土压力的计算公式。对比了不同孔隙水压力条件下土体强度指标的取值对侧向土水压力计算的影响。最后对侧向水土压力计算中土体强度指标的取值给出了建议。
Based on the theory of effective stress and Rankun earth pressure theory, the problems of lateral water and earth pressure calculation are analyzed. The calculation of pore water pressure and the value of soil strength index have a great influence on the calculation results of water and soil pressure. Based on the classification suggestion of pore water pressure, the formula of lateral water-soil pressure under several different pore water pressures is given. The influence of soil strength index under different pore water pressures on the calculation of lateral soil water pressure was compared. Finally, some suggestions on the value of soil strength index in calculating lateral water-soil pressure are given.
