主次固结简化计算方法

本文忽略土的粘性对孔隙水压力消散的影响，对同一时刻发生的主、次固结分别考虑，按简单的数学表达式计算后叠加得到总固结沉降。这种简化方法的特点是计算简便，可求得不同时刻的主次固结比，考虑了有效应力历史对次固结变形的影响，实例计算结果表明方法是合理可行的。

A simplified computation method for primary and secondary compressions

The author of this paper assumes that the viscosity of clay structure has no influence on the dissipation of pore pressure, then, proposes a simplified method of .settlement cal-culation, in which the primary and secondary compressions are calculated separately, and their summation is the total settlement at any time. The characteristics of this meth-od are simple, being able to obtain the ratio of primary to secondary compression at any time and taking into account of the effect of effective stress history on the secondary compression. Comparisons of computation results show that this method is correct and practicable.
