计算地基沉降分层总和法缺陷的分析及改进

分层总和法是计算地基沉降普遍采用的方法，但它本身存在的缺陷常常造成较大的误差。本文根据误差分析并通过大量有限元计算，查明了误差的大小及分布规律，并得出了适用于均质地基及一般层状地基的修正方法。通过工程实例验证了本文方法，本方法对分层总和法的修正优于地基基础规范法。

Analysis and amendment of layerwise summation method for calculation setting of ground

Layerwise summation method is a common way used for settlement computation of ground, but it results in larger error usually, because of itself failing. In the result of analysis of the error and the finiteelement method calculation, we have found the distribution and quantity of the error and obtained modifiedfactor of settlement computation for homogeneous soil and common lay6red soil subgrade.The result ofthis method is proved by real engineering, it is good than the method suggested by code of subgrade andfoundation.
