摘要

为了研究层状岩体的压缩破坏特征，并建立相应的理论描述模型，利用快速拉格朗日元法对三轴压缩情况下的层状岩体进行数值计算，分析了层状压缩强度与结构面倾角的关系，建立了相应的理论模型。利用所建模型，对参考国外文献中的试验结果进行描述，并探讨了加载速率和岩体压缩强度的关系。结果表明：所建拟合模型能够较好描述层状岩体的强度特征，得到了数值试验和室内试验的验证；岩体压缩强度随加速速率增大而增大，二者符合线性关系特征。

Abstract

In order to study the compressive failure characteristics of layered rock mass and build the corresponding theoretical model

the fast lagrangian method was adopted to address numerical simulation of the layered rock mass under triaxial compression. The relationship between compressive strength and inclination of structure plane was analyzed

and a theoretical model was proposed to describe their relationship. The test data from the foreign references were described by the theoretical model and the relationship between loading velocity and the compressive strength was analyzed. It was shown that

the fitting model can well describe the strength characteristics of stratified rock mass

which was validated by the numerical test and laboratory test. And the compressive strength of rock mass increased linearly with the increase of loading velocity. 
