Abstract
Section DK683+938 ~ DK684+004 of Dongziya tunnel belongs to shallow uneven pressured tunnel with large section and passes through fault fracture zone. The project adopted common excavation methods including triple-bench with reserved core method, CRD method and two side heading method. In this paper, the numerical simulation results of three excavation methods were compared by using Flac 5. 0 software, and it has been concluded that two side headings excavation with the shallow side heading excavated first could effectively control tunnel periphery displacements, which ensured engineering quality and construction safety.关键词
