摘要/Abstract

摘要： 岩爆是世界岩石力学与工程研究的前沿,也是制约我国深部战略实施的安全难题。岩爆防控的重点在于机理研究,而刚度理论是岩爆机理研究的重要内容。通过调研大量岩爆刚度理论研究文献,系统归纳了岩爆刚度理论的发展历程、试验方法与典型试验结果、爆体—围岩系统模型与岩爆判据。研究表明:① 刚度理论源于能量理论,经过丰富发展但仍难单一圆满解释岩爆机理;② 刚度试验机演变推动了刚度理论试验由控制岩样刚度向控制试验机刚度转变,岩爆发生的必要条件是试验机刚度低于岩样,且其烈度随着两者刚度差增大而增大;③ 岩爆刚度系统模型将爆体与围岩视为弹塑性组合体,考虑岩样自身储能能力的系统模型更符合实际;④ 现有刚度计算方法主要围绕室内岩样和试验机,且基于刚度理论的岩爆判据仍局限于判别岩爆是否发生。通过分析刚度理论研究现有问题, 展望了动态变刚度试验、不同等级岩爆的刚度理论判据与基于工程实例的原位岩爆刚度理论研究等进一步研究方向。分析结果可为岩爆刚度理论研究与工程应用提供参考。

Abstract: Rockburst is a frontier issue in the field of rock mechanics and engineering worldwide and a safety challenge that restricts the implementation of deep mining strategies in China. The key to rockburst prevention and control lies in the study of its mechanism,and the stiffness theory is an important aspect of this study. By reviewing a large number of study papers on rockburst stiffness theory,this paper systematically summarizes the development history of the stiffness theory,the experimental methods and typical experimental results,the rockburst body-surrounding rock system model,and the rockburst criteria. The study results show that:① The stiffness theory originated from the energy theory and has been enriched and developed,but it is still difficult to fully explain the mechanism of rockburst;② The evolution of the stiffness testing machine has driven the stiffness theory experiments to shift from controlling the stiffness of the rock sample to controlling the stiffness of the testing machine. The necessary condition for rockburst occurrence is that the stiffness of the testing machine is lower than that of the rock sample,and the intensity of rockburst increases with the increase of the stiffness difference between the two;③ The rockburst stiffness system model regards the rockburst body and the surrounding rock as an elastic-plastic composite body,and the system model considering the energy storage capacity of the rock sample is more in line with the actual situation;④ The existing stiffness calculation methods mainly focus on indoor rock samples and testing machines,and the rockburst criteria based on the stiffness theory are still limited to determining whether rockburst occurs. By analyzing the existing problems in the stiffness theory study,this paper looks forward to further study directions such as dynamic variable stiffness tests,stiffness theory criteria for different grades of rockburst,and in-situ rockburst stiffness theory study based on engineering cases. The analysis results can provide reference for the theoretical study and engineering application of rockburst stiffness.
