湿喷钢纤维混凝土在隧道单层衬砌中的应用

摘要

喷射混凝土技术,已经成为地下工程和岩土工程支护中最有效的支护手段之一,它可以配合其它支护构件或单独地作为结构的永久性支护.结合钢纤维喷射混凝土单层衬砌的研究现状、单层衬砌支护机理以及湿喷钢纤维混凝土的力学特性等,介绍了在宜昌-巴东高速公路峡口隧道斜井中的应用,对同类工程具有一定的借鉴作用.%The shotcrete technology has become one of the most effective means for supporting in underground engineering and geotechnical engineering, it could be taken as the structure's permanent support and protection, or along with other support and protection components, maintain the structure long-term stability and safety handling. Here, combining with the research status, supporting mechanism and mechanical characteristics of the steel fiber reinforced shotcrete in single layer tunnel lining, the application of the shotcrete in the inclined shaft of Xiakou Tunnel in Yichang-to-Badong Expressway is introduced, which could be used as references to similar projects in the future.
