摘　　要：为解决阿萨汉一级水电站引水隧洞底拱混凝土衬砌技术难题,在实际工程建设中,设计制作了3套无轨滑模,不仅加快了工程进度、降低了施工成本,也较好地解决了隧洞底拱衬砌中常见的气泡麻面多的质量缺陷问题,可为其他类似长距离隧洞混凝土衬砌施工提供借鉴和参考。Three sets of raillesssliding formworksare designed and manufactured in the actual project construction in order to solve the technical problem of concrete lining for the bottom arch of the water diversion tunnel in Asahan No.1 Hydropower Station.It accelerates the project progress and reduces the construction cost on the one hand.It also solves the common quality defects of many bubble pockmarked in the tunnel bottom arch lining on the other hand.It can provide reference for other similar long distance tunnel concrete lining construction.
