悬臂式挡土墙底板结构计算方法探讨

On Methods for Calculating Stresses in Bottom Slab of Cantilever Retaining Wall

对悬臂式挡土墙内力计算所使用的反力直线分布法和弹性地基梁法进行了对比研究,结果表明两种方法的计算结果存在显著差异,有时甚至内力的符号也不相同,前者弱化了地基反力分布的不均匀性,地基反力和底板内力的极大值均明显偏小.分析表明,使用弹性地基梁法计算出的成果较为可靠.

Based on the comparative analysis on the method of linear distributed reaction and method of beam on elastic foundation, we found out that a difference is existed between the results of these two methods. The former weakened the non -uniformity of the reaction distribution, so the maximal stress in the bottom slab is notable smaller. Hence we consider that the result of the later is rather reliable than the former.
