| 摘 要： | 根据库伦土压力的计算原理,从滑动土楔处于极限平衡状态时力的静力平衡条件出发,推导出了计算粘性土或无粘性土被动土压力的公式.该公式适用于均布荷载作用于挡土墙后任意位置.对重力式挡土墙设计中土压力的计算具有一定参考价值.

| Abstract: | According to the Coulomb's earth pressure theory,from the condition of the static equilibrium of the force when the slide wedge is in limit equilibrium,a formula is derived for the calculation of passive earth pressure of cohesive or non-cohesive backfill soils.This formula could be used in the calculation of earth pressure with superimposed load uniformly distributed on any location of ground surface behind the retaining wall.Some suggestions are proposed to the calculation of earth pressure in gravity retaining-wall designs. |
