软岩渗流规律研究进展
|
摘要
在前人研究的基础上,介绍了软岩的概念和分类,指出按成因可将软岩分为原生软岩和次生软岩;从流固耦合的角度讨论了软岩渗流的数学模型、实验分析和数值模拟的研究现状;从应力与裂隙的相互作用关系方面分析了软岩和硬岩渗透性差异的理论原因。最后针对软岩渗流的研究工作和实际工程问题提出了一些展望。
The concept and classification of soft rock on the basis of previous studies is introduced.Soft rock can be classified into primary soft rock and secondary soft rock,according to its formation conditions.The present status of research on the permeability of soft rock with fluid-solid coupled theory is described,with discussion of mathematical models,experimental studies and numerical simulations.The theoretical reasons for differences in the permeability of soft rock and hard rock are analyzed,in consideration of the relationship between stress and cracks.Finally,some prospects for future research are presented.
