地基沉降计算方法分析与改进

Analysis and Improvement on Methods of Calculating Subgrade Settlement

本文分析了几种常见的计算地基沉降的方法,着重介绍了考虑应力历史、侧向变形和有效应力对分层总和法的改进。提出影响地基沉降计算准确度的是:方法本身能否反映地基的成层性和非均质性;能否考虑到土的非线性特点。

Some common methods of computing subgrade settlement are analyzed in this paper. The influence on the stratified sum methods of stress history in subgrade,lateral deformation and effective stress paths was analyzed. The following factors affect the accuracy of final computing results; soil stratification and heterogeneity, soil nolinearity, and numerical precision of a method.
