摘要
就三台阶七步开挖工法及CRD工法的优缺进行分析和对比,并在2种工法的基础上做综合评价并改进,提出核心土加临时仰拱台阶法的新施工思路和方法,以求对隧道开挖工法进行补充和完善。
CRD excavation method and 3-bench 7-step excavation method are compared, analyzed and evaluated in the paper. Furthermore, a new excavation method, i. e. , bench method with core soil and temporary invert is proposed so as to enrich the tunnel excavation method.
