洪家渡混凝土面板堆石坝渗漏分区监测设计

Design on zoning seepage monitoring on Hongjiadu Concrete Face Rockfill Dam

在洪家渡水电站面板堆石坝安全监测设计中,针对峡谷地区两岸不对称这一工程特点,吸取和借鉴已建工程的成功经验,抓住大坝的变形特征和变化规律,提出了渗漏量分测思路,对分测渗漏量的方案和结构型式进行了研究并付诸了实施,达到了掌握在不对称河谷面板堆石坝出现非对称变形时,引起不同部位渗漏量变化情况的目的,可为工程安全运行维护提供可靠的依据。

During the design of the safety monitoring on the concrete face rockfill dam for Hongjiandu Hydropower Station, the concept of conducting the seepage monitoring in zones with the deformation features and the changing law of the dam is suggested by taking the successful experiences from the other existed projects concerned based on the engineering feature of the asymmetry of both the banks therein, for which the zoning seepage monitoring plan and the structural pattern are studied and conducted as well. With this monitoring method, the changes of the seepages at various locations under the condition of asymmetrical deformation occurred in a concrete face rock fill dam constructed on a asymmetrical valley can be obtained to make a reliable basis for safe operation and maintenance of the project.
