摘要

基于有效应力原理，结合弹塑性几何方程、本构方程及平衡方程建立了应力场控制方程。依据流体力学中的质量守恒原理建立了煤层气、水和煤岩体固体颗粒的渗流场方程；以上方程再配以辅助方程和定解条件构成了应力作用下煤层气-水流固耦合的数学模型，并对简化模型进行了单相流流-固耦合数值模拟分析，得到了压力动态分布曲线，分析了耦合和非耦合情况对压力分布的影响，进一步为煤层气流-固耦合分析提供了一定的理论基础。

Abstract

Based on effective stress theory

combining elastoplasticity geometry equation

constitutive equations and balance equation

stress field equation is established. By mass conservation equation of hydromechanics seepage flow field equation of coal bed gas

water and coal rock soild grain is established. These equations

secondary equations and fix solution condition form mathematical model of coal bed gas-water fluid soild coupling under stress. Using predigesting model to analyze single phase fluid soild coupling

distributing curve of pressure dynamic is obtained

effect of pressure distributing in coupling and non-coupling

so privide theory base for analysis of coal bed gas fluid solid coupling is analyzed.
