论文摘要
提出了一个用于矿山胶结回填的构造模型。弹性模量密度和压力依赖性的四个公式，摩擦模量摩擦角的密度和压力依赖性的五个公式和弹性模量的年龄依赖性和有效凝聚力的四个公式被与Plotical-Coulomb-Coulomb-Coulomb-colybocticition一起纳入了同型低弹性中，并以完美的可塑性框架和Ploxise sys in ser-Dectine os ser-Dectine syse-Dectine os ser-dectine os ser-dectine os ass yser-dectient。当非线性弹性和年龄依赖性都关闭时，这个家庭包括标准的Mohr-Coulomb，Bolton，Leps，Barton和Hoek-Brown模型。在本文中，介绍了模型的表述，概述了数值实现的基础，并以验证剂量的固定式回填层的案例历史记录为示例。
A family of constitutive models for mine cemented backfill is presented. Four formulas for the density- and pressure-dependency of elastic moduli, five formulas for the density- and pressure-dependency of friction angle and four formulas for the age-dependency of the elastic moduli and effective cohesion are incorporated into an isotropic hypoelasticity with Mohr-Coulomb perfect plasticity framework and implemented in PLAXIS as a user-defined material model. This family includes the standard Mohr-Coulomb, Bolton, Leps, Barton and Hoek- Brown models as trivial cases when both nonlinear elasticity and age-dependency are switched off. In this paper, the formulation of the models is introduced, the basis of the numerical implementation is outlined, and a case history of the application to the cemented backfill of a sublevel stoping mine is presented as an example.
