混凝土面板堆石坝填筑技术在大雪山水库工程中的应用

Application of concrete face rockfill dam filling technology in Daxueshan Reservoir Project

混凝土面板堆石坝填筑技术是整个拦河坝施工控制环节中比较重要技术,采取合适的填筑技术可以有效提高坝体填筑料密实度,以此来解决拦河坝不均匀沉降及大幅度沉降等问题。本文以大雪山水库为例,从坝体填筑控制标准、坝体填筑工艺流程、坝体填筑现场检测结果等方面,详细介绍了混凝土面板堆石坝的填筑技术。采用此填筑技术可有效改善坝体和面板的应力变形特性,防止后期堆石料有较大位移以及混凝土面板产生挤压破坏。

Concrete Face Rockfill Dam Filling Technology is a more important technology in the whole borage construction control link. Appropriate filling technology is adopted for effectively improving the dam filling compactness , thereby solving the problems of barrage uneven settlement% serious settlement, etc. In the paper, Daxueshan Reservexample, the filling techndogy of concrete face rockfill dam is introduced in detaii in the aspects of dam body filling control standard, dam body filling process flow, dam body filling field test result, etc. The filling technology can be adopted for effectively improving the stress deformation characteristics of dam body and face, and preventing subsequent larger displacement of rockfill dam, and extrusion failure by the concrete face.
