文中提出一个由切线单轴压缩模量、杨氏模量和剪胀系数三个参数组成的增量型非线性应力应变模式,适用于各种土类在填筑过程中的应力应变计算,特别是粘性土的有效应力应变计算和堆石坝的计算。三个计算参数可以通过常规压缩试验和三轴试验测定,文中讨论了几种可能的曲线拟合法以求取有关的计算常数。
An incremental non-linear stress-strain model consisting of three parameters of tangent uniaxial compression modulus, Young’s modulus, and dilatancy coefficient is proposed in this paper. It is applicable to the calculation of stress and strain in various soil types during the filling process. In particular, effective stress and strain calculations for cohesive soils and calculations for rockfill dams. The three calculation parameters can be determined by conventional compression tests and triaxial tests. Several possible curve fitting methods are discussed herein to obtain the relevant calculation constants.
