摘要
根据新建贵广铁路四寨二号隧道安全下穿厦蓉高速公路瑞坡隧道施工实例,在具有不均匀动荷载的浅埋围岩中修建大断面铁路隧道要保证其上部行车的安全,是隧道施工中的一大难题。通过对下穿过程中采用中隔墙(CRD)法施工取得成功的经验进行阐述、验证。
According to the example of newly built four stockade 2th tunnel safely under-traversing Rui slope tunnel construction of Xiamen Rongjiang expressway,the construction of the railway tunnel of large cross section in shallow surrounding rock of non-uniform dynamic load to ensure the safety of its upper traffic is a major problem in the tunnel construction.This paper conducted the elaboration and validation on successful experience obtained in under-traversing using CRD construction.
