摘要
阐述了岩体水力劈裂两个层面的涵义.从单裂纹的水力劈裂模型、实验研究、数值仿真技术、裂纹内水压力分布等介绍了国内外的理论研究、方法和成果.分析了水利水电等工程中的水力劈裂与人工致裂边界条件的不同.最后,提出单裂纹水力劈裂需研究的几个问题.
Two meanings of the rock′s hydraulic fracturing are explained, and the theories, methods and achievements of the hydraulic fracturing of rock and concrete materials at home and abroad are reviewed from such aspects as modeling, experimental studies, numerical analogy techniques and fracture′s internal water pressure distribution. The boundary condition differences between natural power and artificial driven fracturing in hydraulic and hydroelectric engineering are presented. Finally, several problems of hydraulic fracturing on a single fracture to be studied are forwarded.
