【摘要】 在对层状岩体结构及力学特性分析的基础上，将含夹层岩体视为一个完整的力学系统，建立了含夹层岩体组合系统力学模型，揭示了含夹层岩体的破坏及失稳机理，并研究确定出含夹层岩体稳定性的判别指标，为层状岩体稳定性的控制设计提供了依据。最后，通过一工程实例分析了确定含夹层极限厚度的方法以及提高系统稳定性的措施。更多还原

【Abstract】 Based on the analysis of stratified rock mass structure and its mechanical properties, the rock mass with interband is considered as a whole mechanical system. The mechanical model of combination system for rockmass with interband is established. The failure and unstability mechanism of rockmass with interband is revealed. The evaluation index of stability of stratum with interband is formed and can be used to control design of stratified rockmass stability. Finally, the method to determine the limited interband thickness and the technology to improve system stability are presented with an example.更多还原
