以某一建造于山坡上的多级挡土墙工程为例,对作用在多级挡土墙下墙后的土楔体,在按实际确定第一破裂面的情况下,采用基于库伦土压力理论的图解法确定第二破裂面并求得其主动土压力,进行抗倾覆、抗滑移稳定性以及地基承载力验算。挡土墙建成已有两年多的时间,使用情况良好,表明该分析方法合理可行。 Taking a multi-level retaining wall project built on a hillside as an example, an earth wedge acting behind the wall behind a multi-level retaining wall is determined according to the actual Coulomb earth pressure Theoretical graphic method to determine the second rupture surface and find its active earth pressure, anti-overturning, anti-slip stability and checking of foundation bearing capacity. Retaining wall has been completed more than two years, the use of good condition, indicating that the analysis method is reasonable and feasible.
