扰动粗粒土修正Duncan-Chang模型建立方法及应用
|
摘要
以东北地区三种常见粗颗粒土大型三轴固结排水剪切试验为基础,通过建立相对密实度与初始剪切模量、峰值强度的函数关系,结合扰动状态理论,提出考虑扰动的粗颗粒土非线弹性本构模型的构建方法。
This paper is based on the large-scale triaxial consolidation drainage shear test of three common coarse-grained soils in Dongbei area.By establishing a function of the relative compactness with initial shear modulus and peak intensity,then through combining disturbance state theory,we propose a method for constructing a non-linear elastic constitutive model of coarse-grained soil which considers disturbance.
