    摘要:

    现行考虑土拱效应的挡土墙主动土压力方法未考虑中主应力的影响,不能全面的反映土体的三维受力特性对挡土墙主动土压力的影响。本文根据空间滑动面准则(SMP准则),推导了考虑中主应力影响的侧向主动土压力系数公式及主动土压力分布公式。结果表明:考虑中主应力的SMP准则计算的主动土压力较Mohr-coulomb计算的结果小一些,更接近试验结果。因而,在考虑土拱效应计算挡土墙主动土压力时,考虑中主应力发挥土体的材料强度潜力,对于工程有一定的意义。

    Abstract:

    It was the defect that the intermediate principal stress wasn’t considered when analyzing the lateral active earth pressure behind retaining wall considering the soil arching effect. In order to consider character of the three dimensional soil strength, the formula which calculated the coefficient of lateral earth pressure and the distribution of lateral active earth pressure were derived based on the spatial mobilized plane strength criterion which could consider the effect of intermediate principal stress. Also, the formulas that calculated the magnitude and the point of application of lateral active earth pressure were derived. According test data, the results by the SMP criterion was more closed than the results by the mohr-coulomb strength criterion. So it has an important significance to calculate the distribution of lateral earth pressure and the total lateral earth pressure, the height of total earth pressure when considering the soil arching effect by proposed method.
