摘要
渗漏评价是混凝土面板坝设计中的重要问题,对大坝的设计、运行管理及决策都有着重要意义。基于国内外已建67座面板坝的运行监测成果,运用面板综合渗透系数法,提出了面板坝渗漏值的工程类比与评价方法,给出了量化表达方式和算例,可供混凝土面板坝工程类比与评价参考。
Leakage evaluation of concrete face rockfill dam （CFRD） is an important issue in dam design, and has great influence on dam design, operation and management and decision-making. Based on the monitoring data of 67 constructed CFRDs in domestic and abroad, the engineering analogy and evaluation method on leakages of CFRD is proposed after adopting the comprehensive permeability coefficient of concrete face, and a quantitative formula and its application in a case study are also given herein. The new method can be as reference to engineering analogy and evaluation of CFRD project.
