| 摘 要： | 本文在已有研究成果的基础上,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平衡条件出发,考虑实际地震中对挡土墙稳定性最不利的情况,推导出了计算黏性土或无黏性土主动土压力的公式。该公式适用于均布荷载作用于挡土墙后任意位置。对地震多发区考虑水平惯性力作用下重力式挡土墙设计中土压力的计算具有一定参考价值。

| Abstract: | Based on the Coulomb's earth pressure theory,under the condition of the equilibrium of the forces when the sliding wedge is in limit equilibrium,a formula is derived for the calculation of active 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 at any location of ground surface behind the retaining wall.Some suggestions are put forward for the calculation of earth pressure in gravity retaining wall design in seismic region considering the horizontal inertial force. |
