广义 Voigt 模型模拟的饱和土体轴对称固结理论解

本文采用广义 Voigt 模型,导出了自由应变条件下考虑井边涂抹作用,等垂直应变条件下考虑涂抹和井阻作用的饱和粘弹性土体轴对称固结理论解.解的形式有广泛的适用性,可概括 Barron 弹性解和郭志平粘弹性解等,故它更方便于工程应用.研究工作还表明:由于推导有误,关于这一问题的 Barron 解不满足固结基本方程;由于设置条件失当,传统的 Carrillo 定理不再适用于饱和粘弹性土体情况.

Theoretical Solution to Symmetrical Consolidation of Saturated Clays With Generalized Voigt Model

In this paper the solutions to symmetric consolidation of saturated viscoelastic clays are derived with the generalized Voigt model,taking account of peripheral smear of a drain well under free strain condition and peripheral smear and resistance under equal vertical strain condition.The original solutions,such as Barron's elastic solution and Guo's viscoelastic solution,are only special ones of the generalized solution in this paper.The author points out that Barron's solution for the case of peripheral smear and resistance under equal vertical.strain condition is incorrect,and that Carrillo's theorem can not be applied to the case of two or three-dimensional consolidation of the saturated viscoelastic medium.
