根据双村隧洞高湿度黄土不稳定围岩的施工监测结果，探讨隧洞变形随施工因素的变化规律和压力的分布规律，提出控制这类隧洞施工稳定性的方法和标准。这一研究较好解决了汉村隧洞的技术难点，并为施工带来显著效益。
According to the construction monitoring results of unstable rock with high humidity and loess in Shuangcun tunnel, the variation law of tunnel deformation and the distribution of pressure are discussed, and the methods and standards for controlling the stability of such tunnel construction are proposed. This research solves the technical difficulties of the Hancun tunnel and brings significant benefits to the construction.
