摘要
通过探讨地基土自重应力对地基土体变形模量影响,采用原始积分法计算地基土的附加应力,将自重应力作用后的变形模量用于地基土附加应力作用时的沉降计算中,提出了利用分层总和法计算地基沉降的简化计算方法.通过工程实例的计算与分析,并与实测结果及其它方法计算结果进行比较,证明该方法简单可行,可准确计算地基沉降.
In this article,a settlement calculation method for foundation soil is presented.Through studying the effect of gravity stress on foundation-soil deformation modulus,using a primitive integral method to calculate the additional stress of the soil and applying the deformation modulus after influenced by gravity stress to the settlement calculation of the additional stress of the soil,a simplifying computational method for settlement of foundation soil using a layer-wise summation method is put forward.By comparing the computation and analysis of an engineering example with results by the method of code for design of building foundations and other methods,it is shown that the proposed method is simple and feasible and the results agreed well with the observations.
