Research on the Failure Characteristics of Different Types of Fractured Rock Masses: A Review of Theories, Methods, and Applications

摘要: 裂隙岩体作为地质工程中的重要组成部分，其力学行为对工程设计与安全评估具有重要影响。本论文综述了裂隙岩体的破坏机理，重点论述单裂隙和多裂隙系统的破坏特征。通过分析裂隙的几何参数、加载条件及其相互作用，揭示了裂纹萌生、扩展与贯通的机制。现有研究在三维裂隙网络、裂纹萌生过程的实时观测和动静荷载耦合作用下的破坏特征等方面存在局限。论述该领域未来将通过三维数值模拟和精细化实验，探索裂隙岩体的复杂破坏行为，填补相关研究空白。将为岩体力学和工程稳定性评估提供理论支持，推动裂隙岩体破坏机理的深入理解。

Abstract: As an important component in geological engineering, the mechanical behavior of fractured rock masses has a significant impact on engineering design and safety assessment. This paper reviews the failure mechanisms of fractured rock masses, focusing on the failure characteristics of single-fracture and multi-fracture systems. By analyzing the geometric parameters of fractures, loading conditions, and their interactions, the mechanisms of crack initiation, propagation, and penetration are revealed. Existing studies have limitations in aspects such as three-dimensional fracture networks, real-time observation of crack initiation processes, and failure characteristics under coupled dynamic and static loads. The discussion suggests that future research in this field will explore the complex failure behavior of fractured rock masses through three-dimensional numerical simulations and refined experiments, filling gaps in relevant studies. This will provide theoretical support for rock mechanics and engineering stability assessment, and promote a deeper understanding of the failure mechanisms of fractured rock masses.
