摘要
本文将秦岭隧道岩爆等级分为无岩爆、弱岩爆、中等岩爆和强烈岩爆四级，选取应力强度比、断层发育情况、围岩类别、地形影响、地下水发育等五个因素作为评判指标，采用模糊综合评判方法对秦岭铁路隧道岩爆的预报进行了研究，其研究成果在现场得到较好的应用。
The rock burst of Qinling Railway Tunnel is divided into 4 grades:no, slight, middle, and strongones. The fuzzy synthetic judgement method is applied to the burst prediction of the tunnel according to these factors such as the ratio of earth stress and rock compression strength, the fault influence, the rounding rock grade, the topography, and the groundwater. The method is proved successful mn practive.
