岩溶隧道在勘察设计阶段很难对岩溶发育情况给出准确具体的评价,导致此阶段进行的围岩级别划分与实际施工阶段揭露的情况存在差异。因此,有必要对岩溶隧道进行施工阶段的围岩动态分级。本文通过对岩体基本质量指标的综合修正,得到岩溶隧道围岩动态分级的定量方法,并成功应用于仙人洞隧道岩溶围岩的动态分级中,使围岩的分级与实际情况更加接近,确保了施工的安全与合理。

The accurate evaluation of karst development situation is hard to given in the investigation and design phases for karst tunnel that cause much difference between the classification results in these phases and those revealed situation during construction,so it＇s necessary to establish dynamic classification method for karst tunnel during construction.The article got the quantitative assessment method of surrounding rock dynamic classification for karst tunnel through the comprehensive revision of basic quality indicator of rock.And the method is successfully applied to the karst surrounding rock dynamic classification of the XianRendong tunnel,which made the surrounding rock classification closed to the actual conditions and ensured the safety and rationality of the construction.
