摘　　要：根据丰宁水电站混凝土面板砂砾石坝高程1025m层和1040m层水管式沉降仪和引张线的施工,得出了在土石坝中广泛采用的、传统的坑槽式埋设方法已不适应现代砂砾石混凝土面板坝施工的结论,而水管式沉降仪和引张线的施工是采用在填筑面上直接埋设,不用开挖坑槽,简单易行,便于操作的施工方法。According to the construction of water tube settlement meter and tension line for 1025m and 1040m floors of concrete face slab sand-gravel dam of Fengning Hydropower Station,it is concluded that the traditional pit-and-trough embedment method widely used in earth-rock dam is no longer suitable for the construction of modern sand-gravel concrete face dam.Water tube settler and tension line can be directly buried on the filling surface without excavating the pit and trench.It is a simple and convenient construction method.
