摘要
为提高对沉降计算的可靠性与方便性,提出了一种基于应力路径的实用沉降计算方法。依据应力路径法原理,采用由Skempton(司开普顿)孔隙水压力方程得出的有效应力路径方程来表达应力路径,得出了沉降计算的实用计算式。所提出的计算式具有形式简洁、参数易确定、方便实用等优点。工程实例分析验证了该方法的可靠性,可为实际工程的沉降计算提供参考。
In order to raise the reliability and convenience of calculating settlement,a practical method for calculating settlement based on actual stress path is proposed.According to stress path method,a practical expression for calculating settlement is put forward by using effective stress path equation derived from Skempton pore water pressure equation,which has the advantages of explicit conception and simple form with the parameters of expression easy to be obtained.An engineering case study shows that the proposed method is reliable;it can be taken as a reference for engineering applications.
