| 摘 要： | 本文从硬粘土的主要工程特性之一的超固结特性出发,采用有限单元法计算开挖边坡的位移,计算中采用分级开挖、线性弹性模型及以先期上覆土层厚度H_0代替通常所采用的超固结比OCR,同时也考虑到其它的变形参数:侧压力系数k_0、泊桑比μ及回弹模量E_0讨论了这些参数对水平位移及垂直位移的影响及边坡的变形规律

| Abstract: | Based on the overconsoJidation, which is one of the propersties of leek, the calculation of displacement for excavation in leek by FEM is put. In calculation stage excaration, linear elastic medel and a thickness of preconsolidation overburden layer Ho taken instead of OCR are adorsted and other deformation parameters coefficent of earth pressure at rest ko, Porsson's ratio n and modulus of resilience E are consi-derated, Their influence on the horicontal and the vertical displacement and on the deformation of slope is discussed. |
