    摘要:

    本文基于石膏模型试验的结论,借助断裂力学理论,着重讨论了含 X型断续节理岩体的压剪断裂强度特性及破坏机理。结合有限元数值模拟计算,分析研究了节理方位、围压大小对这类岩体强度的影响。

    Abstract:

    In this paper,the strength properties of rock mass withrows of intermittent bidirectional cross joints by simulating models arediscussed.Work has been done on finding the failure mechanism of therock mass as well as the influence of joint direction and lateral pressureon tne strength of the rock mass.At the end of the paper,model testresults ahd FEM analyses are presented and strength criteria for thiskind of rock mass are proposed.
