地下工程中的流—固耦合问题的探讨

叙述了涉及煤岩体－流体相互作用的地下流－固耦合理论的进展概况和流－固耦合作用的基本概念以及存在的工程背景。主要讨论了地下工程中液＋固、气－固、气－液－固、热－固、流等耦合作用的机理、建模方法、如系模型、数值分析思路及方法及未来工程应用中主要存在的问题。研究结果表明，进一步发展地下流－固耦合理论对解决地下工程的一系列问题有着重要意义，多因素耦合分析是今后研究流－固耦合问题的关键。

The Research of Fluid-solid Coupling in the Ground Engineering

This paper depicts the theory development in the ground fluid—solid coupling about coal—rock—fluid interaction and the basic concept of fluid－solid coupling and the engineering background,mainly discussing the coupling mechanism of fluid-solid, gas-solid, gas—fluid—solid, heat-solid-fluid, the establishing method, the idea of numerical value analysis and method,numerical model the main problem in the future engineering. The results show that fluid—solid coupling theory forward are developed in the ground are imporfant to solve a serial of problems in the ground engineering and multifactor coupling analysis the key to study fluid—solid coupling problems.
