统一固结理论在吹填土中的应用

本文介绍了包含六个基本方程式的统一固结理论,它将土体主固结和次固结阶段统一考虑,认为土体的应力应变关系不是唯一的,而是应变速率的函数。通过一系列室内固结试验及渗透试验求出了一种吹填软粘土的固结参数,采用有限差分法将统一固结理论应用于室内试样和现场土体的固结计算,试验和计算结果表明,统一固结理论具有普遍适用性和合理性。

Application of Unified Theory for Consolidation in Dredger Fill

In this paper,a unified consolidation theroy is introduced which combines the primary and secodary consolidation stages under the control of a set of six equations.It is considered that the rela- tionship of clay between stress and strain is not alone,but a function of strain rate.Consolidation pa- rameters are obtained from a number of laboratory consolidation tests on a slurry clay,The results cal- culated using FD method by the unified consolidation theory on laboratory samples and thick field stra- ta show that the unified theory is reasonable and practical.
