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。
Based on the analysis of the structure and mechanical properties of layered rock masses, considering the intercalated rock mass as a complete mechanical system, the mechanical model of the composite system with intercalated rock mass is established to reveal the failure and instability of intercalated rock masses Mechanism and determine the discriminant index of the stability of the intercalated rock mass, which provides the basis for the control design of the stability of the layered rock mass. Finally, an example is given to determine the method of determining the ultimate thickness of sandwich and to improve the stability of the system.
