地基压缩层深度及沉降的简捷计算法

A Shortcut Method for Calculating Depth of Compressive Deformation Layer and Settlement in Subsoil

本文根据分层总和法的基本概念及表达式给出了变形系数表及变形梯度系数表。变形系数表较地基规范推荐的平均应力系数表减少了近一半的计算工作量,变形梯度系数表则使分层总和法中最繁杂的压缩层深度重复试算简化为一简单线性方程的试算。

Based on the fundamental concept of layer-wise summation method, this paper presents tables for deciding the coefficients of deformation and deformation grade. The table of deformation coefficients is more convenient to apply than the table of average stress as given in the current code. The depth of compressive deformation layer can be quickly decided by using the table of deformation grade coefficients than that by using the conventional method.
