Calculation of active earth pressure in unsaturated expansive soil based on columb earth pressure theory 基于库仓理论的非饱和膨胀土主动土压力计算
Finally the reduced coefficient of active earth pressure has been analyzed in this paper , which further confirmed the formula rationality 最后对主动土压力折减系数做了分析,进一步验证了公式的合理性。
The analysis results indicated that the earth pressure was related to the material in properties pattern , distributed in parabolic pattern , and its value was greater than the active earth pressure 结果表明,此类挡墙墙背土压力的分布与填料及地基材料参数有关,一般呈抛物线形分布;土压力的大小远大于主动土压力。
According to the coulomb ' s earth pressure theory , from the condition of the static equilibrium of the force when the slide wedge was in limit equilibrium , a formula was derivated for the calculation of active earth pressure of cohesive or non - cohesive backfill soils 摘要根据库伦土压力的计算原理,从滑动楔体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主动土压力的公式。
Based on the hypothesis that the rear side of retaining wall is pitching and coarse , and the filling surface is gradient , taking viscous filling as the object of study and using the static balance method , a study has been conducted on the earth pressure on the rear side of retaining wall under the sliding wedge ' s limiting equilibrium condition , and generated a general form for active earth pressure and passive earth pressure 摘要基于挡土墙墙背俯斜、粗糙且填土表面倾斜的情况,以粘性填土为研究对象,用静力平衡方法研究了挡土墙后滑动土楔体达到极限平衡状态时作用于墙背的土压力,提出了主动土压力和被动土压力的一般形式。
