方形浅基础地基极限承载力的理论解

Theoretical Solution of Ultimate Bearing Capacity of Soil under Shallow Square Foundation

根据刚塑性体的静力平衡条件 ,推导了方形浅基础地基承载力的理论解 .该理论解主要由 3方面组成 :粘聚力c、均布超载 q、土体重度γ .与Vesic的半经验分析结果进行了对比 ,二者相似 。

A new theoretical solution of shallow square foundation is presented based on static equilibrium of rigid-plasticity body.It comprises three factors:cohesion,c,over loading,q,and density of the soil,γ.The results of this solution are similar to semi-emperience Vesic solution,which provides a new approach to calculate bearing capacity of shallow square foundation.
