巴贡混凝土面板堆石坝施工期反渗排水设计

Design of reverse seepage for Bakun CFRD during construction stage in Malaysia

关于混凝土面板堆石坝施工期的反渗排水问题,中国混凝土面板堆石坝设计规范(DL/T 5016-1999)只介绍了几种排水方案,但对于如何确定施工期的反渗排水量并没有给出相应的标准或方法。文章简要介绍了马来西亚巴贡混凝土面板堆石坝施工期反渗排水量的确定方法,以及最终采用的反渗排水方案。

With regard to the reverse seepage of CFRD during construction, several schemes were introduced in the Chinese Specifications for Design of Concrete Face Rockfill Dam （DL/T 5016-1999）, whereas no standard or method was stipulated as how to determine the quantity of reverse seepage during construction period. In this paper, the method to determine the quantity of reverse seepage in CFRD for Bakun hydropower project in Malaysia was briefly presented, and the drainage scheme was finally adopted.
