裂隙岩体的流固耦合研究现状与应用展望

裂隙岩体渗流研究主要是考虑流体在岩石裂隙中运动规律,尤其是流体渗流和岩体应力之间的相互耦合作用机理。随着工程应用发展的需要,裂隙岩体的流固耦合研究已成为国内外研究的热点问题。通过对国内外相关文献的分析和整理,从裂隙岩体流固耦合的试验研究、理论模型和数值模拟方法等三个方面的进行了论述,并对其工程应用前景进行了展望。

Present Situation of Research and Prospect of Application of Fluid and Stress Coupling in Fissured Rock Mass

Researches on seepage in fissured rock mass primarily are concentrated on the law of the fluid motion in rock fractures,especially on the coupling mechanism between the fluid flow and the rock mass.With the need of engineering,the research on fluid and stress coupling has become a hot issue in recent years at home and abroad.The present situation of the research is discussed from its experimental study,theory models and numerical simulation methods by searching and analyzing the related literatures.The prospect about its application is also presented at the end of this paper.
