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.
In this paper, a generalized Voigt model is used to derive the theoretical solution of axially symmetric consolidation for saturated viscoelastic soils considering well-stripping and equal vertical strain conditions under free-strain conditions. The solution has extensive applicability. It can be summarized that Barron’s elastic solution and Guo Zhiping’s viscoelastic solution are more convenient for engineering applications. The research also shows that Barron’s solution to this problem does not satisfy the consolidation basic equation due to incorrect derivation; due to improper setting conditions The traditional Carrillo theorem is no longer applicable to saturated viscoelastic soils.
