潜在岩爆评估是工程前期或可研阶段预估工程施工风险、建设成本和规划工程布置中的重要课题，现有单独采用岩爆倾向性或应力与强度之比的评价方法存在不足。文中建议了一种地下工程潜在岩爆问题评估方法，综合考虑了岩石力学特性、围岩质量和地应力三方面的内外在因素，归纳了岩爆对应的地质条件，总结认为岩爆主要发生在II、I类围岩。以体积应变反弯点为卸载控制点，改进了岩爆倾向性指数的试验方法。综合考虑岩石弹性能指数、应力强度比和主应力比3个因素，提出了潜在岩爆指数新指标，并给出了相应界限值，可为工程可研阶段岩爆风险预估提供了一种操作简单、逻辑科学的评估方法。

Potential evaluation of rockburst is an important topic for risk estimation in construction, construction cost and planning project layout in the primary stage or feasibility study stage of the project. There still exist some disadvantages in application of the evaluation method of rockburst proneness or the stress-strength ratio. Therefore, an evaluation method was suggested on the potential rockburst problem, considering three aspects of both the interior and exterior of factors including rock mechanics properties, qualities of surrounding rockmass and in-situ stresses. The corresponding geological conditions of rockburst sections were summarized to conclude that rockburst occurs mainly in II or I grade of surrounding rock mass. The test method of rockburst proneness index was improved to inflection points of volume strain for unloading control points. A new index of potential index of rockburst was put forward by introducing three factors of elastic strain energy index, stress intensity ratio and principal stress ratio. Then, the corresponding threshold values of the new index were presented. The proposed evaluation method provides a simple and scientific way for estimation of rockburst risk in the feasibility study stage .
