在深入分析硬壳层对下卧软土层的封闭作用和扩散作用的基础上,推导了能考虑这两种作用的软土地基临塑荷载计算公式。同时通过对封闭作用产生机理的分析
指出传统的弹性力学分析方法无法考虑封闭作用对软土地基临塑荷载的影响。
Based on deeply analyzing the closure effect and stress dispersion of crust
a critical edge pressure formula of soft clay foundation considering the two effects is derived. At the same time
through the analysis about the generation of the closure effect
it is pointed out that the traditional method in elastic mechanics couldn’t consider the closure effect of the curst .
