摘　　要：尼尔基工程主坝为沥青混凝土心墙土石坝,主坝工程施工采用两期导流方式。一期导流明渠布置在左岸滩地上,由于明渠开挖底高程及明渠段坝体现浇混凝土防渗墙底高程等低于河床常水位,因此采用链槽铺塑作防渗围护施工。本文结合工程实际,对链槽铺塑设计及施工作简要综述。The major dam of Nierji water project is an earth- rockfill dam with asphalt concrete core. The construction diversion is used two stages. The open channel diversion is disposed on the bottomland of the left bank for first stage. Owing to the bottom level excavated the open channel and constructed the concrete cutoff wall is lower than the normal water level of the river channel, so the chain slot spreading membrane is used to construct the impervious works. The paper summarizes the design and the construction of the chain slot spreading membrane combining the project practice.
