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 improve the reliability and convenience of settlement calculation, a practical settlement calculation method based on stress path is proposed. According to the principle of stress path method, the effective stress path equation derived from pore water pressure equation of Skempton is used to express the stress path, and the practical calculation formula of settlement calculation is obtained. The proposed formula has the advantages of simple form, easy to determine the parameters, convenient and practical. The analysis of engineering examples validates the reliability of the method and provides a reference for the settlement calculation of practical engineering.
