摘　　要：应变型岩爆是一种严重危害深地下工程施工安全的工程灾害,其影响因素、物理机制、预测预报等一直存在争议。分析了最近的岩爆研究成果和工程实践经验,认为应变型岩爆的发生与工程地质因素、工程环境因素和人为开挖扰动密切相关,对岩爆孕育的强度理论和能量理论进行了评述,分析了应变型岩爆的致灾力学机理,并指出卸载速率对岩爆发生的重要影响和应变型岩爆的拉伸破坏特征,最后对应变型岩爆的预报、防治理论和方法进行了论述。Strain rockburst is an engineering disaster which severely impairs the safety of underground construction. The study on the evolution law,prediction and prevention of strain rockburst is of great practical importance. This paper summarized the recent researches and engineering practice, including the influence factors, evolution law, physical mecha nism and prevention of strain rockburst. The unloading effect and tensile characteristics of strain rockburst were pointed out with detailed analysis. The reviews can provide guidance for the research and practice in relative fields.
