中文摘要:
      蠕变是岩石一种重要的力学特性,与工程的长期安全稳定和安全密切相关。声发射技术作为一种无损检测手段,被广泛应用于岩石变形破坏研究领域。本文阐述了近年来基于声发射技术开展岩石蠕变特性方面的研究进展,主要包括不同岩性、加载方式、应力水平下岩石蠕变声发射特性,岩石蠕变破坏声发射前兆特征。在此基础上,提出了几点今后需要进一步深入研究的问题。
英文摘要:
      Creep is an important mechanical property of rock, which is closely related to the long-term safety, stability and safety of the project. Acoustic emission technology, as a non-destructive testing method, is widely used in the field of rock deformation and failure research. This paper describes the research progress of rock creep characteristics based on acoustic emission technology in recent years, mainly including the acoustic emission characteristics of rock creep under different lithology, loading methods, and stress levels, and the precursor characteristics of acoustic emission of rock creep failure. On this basis, several issues that need to be further studied in the future are put forward.
