微纤维薄衬砌探讨

Discussion on Micro-fibril Thin-lining

小孤山水电站引水隧洞初设阶段,采用喷锚衬砌。技施阶段,经设计人员认真比较,改为薄衬砌,提高了电站效益。如果在混凝土中加入微纤维,既可节省资金,又可提高电站的安全性,亦可为运行管理提供方便。微纤维薄衬砌是一种好的衬砌形式,应进行大量试验,并予以推广。

During preliminary period, we design shotcrete-ancborage lining for Xiaogushan diversion tunnel. During technique construction period, we change it into thin-lining after careful comparison which improves economic benefit and safety. If can add micro-fibril into concrete, this can not only saving capital and improve the safety of plant but also bring more convenience for management of plant operation. Therefore, micro-fibril thin-lining is a good lining form, it needs to be experimented by great amount and popularized.
