摘要
采用理论分析模型与计算机数值模拟相结合技术,对Ⅱ类围岩条件下的大断面小净距浅埋隧道进行双侧壁法、单侧壁法、台阶法三种施工方案的对比分析,为工程设计和施工提供参考和指导。
This paper analyzed the three construction scheme for the large section low net - distance and shallow tunnel under the condition of class Ⅱ surrounding - rock of dual and single side wall and grade method comparatively, by combining the theoretical analysis and computer simulation technology, and provided reference and guide for tunnel design and construction.
