一、堆石坝钢筋混凝土面板的型式钢筋混凝土面板作为堆石坝防渗型式在国外已广泛采用.我国也正在开展对面板坝的试验研究工作,并选定高95米的西北口水库大坝作为面板试验坝,正在设计的几座大型水库如潘家口,天生桥水电站也采用该种防渗型式的面板坝.实践证明:采用这种坝型坝体堆石量可减到一般堆石坝的65~70%左右,防渗性可靠,即使面板坝发生某些裂缝,漏水,但面板底部设置有级配良好的弱透水性的垫层,因此不会发生大的渗漏,并仍能保证坝体的安全运行.
First, the type of rockfill dam reinforced concrete panels As the seepage-proof type of rockfill dam has been widely used in foreign countries.At the same time, China is also carrying out experimental research on the panel dam, and selected 95 meters high West Beikou Reservoir Dam As a panel test dam, several large reservoirs are being designed, such as Panjiakou, Tianshengqiao hydropower station also use the seepage-proof panel dams. Practice has proved that: the use of such dam rockfill dam volume can be reduced to the general rockfill dam 65 ~ 70%, impermeability and reliable, even if the panel dam some cracks, water leakage, but the bottom of the panel is provided with graded weak impermeable cushion, so there will be no major leakage, and can still guarantee The safe operation of the dam.
