摘要
Abstract
Due to the fact that the air defense section has a large size in the mine tunnel,a different excavation method is usually adopted to ensure the construction safety.However,the air defense section is short in length,which results in frequent switching of the excavation methods in short distance,greatly reducing the construction efficiency.Based on the air defense section of a metro line in Qingdao,this paper investigated the effects of the same method(the step method) and different construction method(the CD method) on the vault crown settlement,ground settlement and clearance convergence through finite element calculation and field measurement.The results showed that the step method is suitable for the air defense section with short length and large cross section,in IV-level sunrounding rocks,which may provide reference for some similar projects.关键词
