Overview of Research on Damage Evolution and Acoustic Emission Precursors of Locked Landslides

摘要: 锁固型边坡作为一种典型的岩质边坡，其稳定性主要受控于锁固段的力学特性，其失稳过程往往呈现出显著的复杂性和突发性特征。随着人类对大自然的过度开采和利用，锁固型边坡失稳问题愈发严重。本文系统阐述了锁固型滑坡的概念模型与研究方法，重点聚焦于数字图像相关(DIC)和声发射(AE)无损监测技术，对锁固段损伤演化规律与识别破坏前兆特征方面的应用现状。并系统地探讨了AE技术与数字图像相关(DIC)技术联合监测的应用价值，总结了当前研究的成果与存在的不足，并对未来多技术融合、智能预警的发展方向进行了展望。

Abstract: As a typical rock slope, the stability of the locked-type slope is primarily governed by the mechanical properties of the locked segment, and its instability process often exhibits significant complexity and suddenness. With human over exploitation and utilization of nature, the instability issue of locked-type slopes has become increasingly severe. This paper systematically expounds on the conceptual model and research methods of locked-type landslides, with a focus on the application status of digital image correlation (DIC) and acoustic emission (AE) nondestructive monitoring technologies in the damage evolution law of the locked segment and the identification of precursor characteristics of failure. It also systematically discusses the application value of combined monitoring using AE technology and DIC technology, summarizes the current research achievements and existing deficiencies, and looks forward to the future development direction of multi-technology integration and intelligent early warning.
