摘要
对近年来围压对脆性材料力学性能影响的研究进行了综述,首先分析了围压对脆性材料力学性能影响的实验研究成果,指出了其在实验条件、实验范围、实验理论等方面存在的问题;其次较系统地总结了脆性材料微观损伤本构模型,讨论了双轴压缩载荷作用下滑移裂纹模型的特性。在此基础上,对脆性材料在围压作用下的力学行为研究进行了展望。
The recent research in the effect of confining pressure on brittle material mechanics is summarized.Firstly,the experimental research results are analyzed,and the research problems are pointed out in experimental condition,experimental area and theoretical base.Secondly,the microcosmic damage constitutive models are summarized systematically,and characters of the sliding crack model under biaxial compressive loading are discussed.On the base of this,the research of brittle material mechanics on confining pressure in the future is put forward.
