水平岩层是指产状呈水平或近水平的岩层,通过对康家院隧道水平或缓倾岩层的稳定性分析,研究了在III级泥岩夹砂岩及砂质泥岩的水平及缓倾岩层中施工的康家院隧道所采用的开挖及支护的相应辅助施工技术。该技术以新奥法原理为基础,对施工工艺、施工措施进行优化,确保了隧道施工安全、有序地进行。 Horizontal rock formation refers to horizontal or near horizontal rock formation. Based on the stability analysis of horizontal or slow-dip rock formation in Kangjianyuan Tunnel, it is studied that in the level of grade III mudstone and sandy mudstone and construction in gently inclined rock Of the Conchuan tunnel excavation and supporting the use of the corresponding auxiliary construction technology. Based on the principle of New Austrian Law, this technology optimizes the construction technology and construction measures to ensure the safe and orderly construction of the tunnel.
