摘　　要：依托西藏林芝市公路改造工程,借鉴工程爆破中可爆性分级理论,提出了一种适用于CO_(2)相变致裂作用下岩体可致裂性分级的层次分析法(AHP)-熵权法(EWM)和云模型分级方法,并利用该方法对某工程岩体进行可致裂性分级评价。研究结果表明:该方法克服了传统分级方法固定评价模式的缺陷;根据可致裂性特点将拟建区域岩体分为二、三、四级。Based on the road renovation project in Nyingchi City,Tibet,referring to the explosibility classification theory,an analytical hierarchy process(AHP)-Entropy Weight Method(EWM)and Cloud Model classification method suitable for rock mass cracking under CO_(2) phase transition has been proposed,which has been used to evaluate the fracture ability of a certain engineering rock mass.The results indicate that the proposed method overcomes the defect of the fixed evaluation model of the traditional classification method.According to the cracking characteristics,the rock mass fracturing grades in the proposed area can be divided into level Ⅱ,level Ⅲ and level Ⅳ.
