多级支护结构体系土压力计算的研究

Multistage supporting structure system of earth pressure computational research

从经典库仑土压力计算理论入手,建立了深基坑多级支护土压力的计算模型,推导出深基坑多级支护土压力计算公式,结合工程实例得出:上级支护对下级支护有一定的影响,且与各级支护之间的开挖深度H和平台宽度W有密切的关系。

Starting from the classical Coulomb earth pressure theory, this article has established a multistage supporting structure of earth pressure computational model in the deep hole, inferred the multistage supporting earth pressure formula combining from some project example in the deep foundation, obtained： the higher authority supporting has the certain influence to subordinate supporting, the excavation depth H and the platform width W are closely related between supporting levels.
