| 摘 要： | 本文通过三个不同尺寸的探头在柔性边界标定罐中的静力触探试验，揭示了临界深度尺寸效应、土体密实度影响等贯入机理。为了获得探头周围土体的应力场和位移场采用了目前能很好反映砂性土变形特性的拉德(P.v.LOde)模型作为土的本构关度场系

| Abstract: | Three cones were used in the static penetration tests in calibration chamber under different boundary conditions. By analyzing the data interpreted from the tests, the author has brought to light the penetration mechanism such as critical depth, cone dimension and soil density effects. In order to get the true stress field and displacement field around the cone. Lade model has been used in the FEM processing, which is commonly considered as the best model in simulating the constitutive relation of sand. |
