摘　　要：挤压边墙作为目前正在推广的一项面板坝施工技术,与传统的上游坝坡施工方法相比,具有工序少、干扰小、施工速度快、利于防洪度汛、表面美观等优点。在白莲河抽水蓄能电站面板堆石坝中应用了该施工技术,采用机械设备在垫层料上挤压形成一道混凝土边墙,避免了传统工艺中对垫层料超填、斜坡碾压、削坡等繁琐工序,不但保证了工程质量,而且改善了面板的受力状态。Comparing with the traditional upstream slope construction method of face rockfill dam, the extrusion side wall technology has advantages of less process, little interference, fast construction, conducive to flood control and good surface appearance. This technology is applied in the construction of the face rockfill dam in Bailianhe Pumped-storage Power Station, in which the machinery is used to extrude a concrete wall on cushion material and traditional processes of cushion material over-filling, slope rolling and slope cutting are cancelled. The extrusion side wall technology not only ensures the quality of construction, but also improves the stress of face slab.
