考虑条形基础相邻影响时双层地基承载力的计算方法

Calculation of Bearing Capacity of Dual-layer Ground Considering the Adjacent Effect of Strip Foundation

本文根据相邻基础应力效应叠加原理 ,分析了产生条形基础相邻影响效应的主要因素及其影响程度。对双层地基承载力确定中应考虑的基础相邻影响效应 ,则采用等效基础宽度的分析方法加以反映 。

The major factors inducing adjacent influential effect on strip foundation and the degree of effect are analyzed herein based on the superposition principle of stress effect of adjacent foundation. Analytic method of equivalent foundation width is used to reflect the adjacent influential effect which should be considered in determining the bearing capacity of dual\|layer ground. Thus calculation of bearing capacity of dual\|layer ground considering adjacent effect of foundation is acquired.
