摘要
针对传统黏性土路基土压力计算理论的不足之处,提出利用极限分析法计算黏性土路基挡土墙的主动土压力,把土的黏聚力作为一个单独的计算因素,推导出相应的计算公式,使之更适合于一般情况下的土压力计算,并通过算例与传统的计算方法相比较,表明极限分析法的正确性和有效性,可用于实际工程。
In view of the shortage of the traditional calculation theory of clay subgrade earth pressure, the limit analysis method is used to calculate the active earth pressure of the clay subgrade retaining wall. The cohesion of clay is considered as a single calculation factor,then the corresponding calculation formula is derived so as to make the formula more suitable for general situations. A calculation example is given and the limit analysis method is compared with the traditional calculation method, which proves the correctness and validity of the limit analysis method. The presented method may be used in practical projects.
