地下工程中的流─固耦合问题的探讨

The Research of Fluid-solid Coupling in the Ground Engineering

叙述了涉及媒岩体一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。

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.
