复合地基承载力下限分析

An lower-bound analysis for estimating the bearing capacity of soils reinforced by columns

首先基于下限定理给出复合单元的平衡和屈服条件,然后将该结果应用到整个复合地基中,推导出复合地基极限承载力的下限值,为进一步的理论研究奠定了基础。

A lower bound of the capacity is determined within the framework of the yield design theory. It takes into account the confining pressure of the foundation and is applicable to a wide range of geometries.
