| 摘 要： | 针对芹山面板堆石坝坝高１２２ｍ、左岸岸坡陡峻，计算剪切变位大（４５ｍｍ）的特点，对面板坝周边缝的止水结构进行了优化改进。通过分析研究和模型试验，将中间的ＰＶＣ止水提至表层，采用表层波形止水结构，这在国内外尚属首例，从目前应用情况看，这种止水结构效果较好。

| Abstract: | According to the characteristics of the Qinshan concrete facing rockfill dam with the dam height of 122m, the steep side in the left bank and large calculated shear deflection (45 mm), the sealing structure of the peripheral joint of the concrete facing rockfill dam has been optimized and improved. Through the analysis, study and model test, the PVC seal in the middle part has been lifted to the surface part and the surface corrugated sealing structure has been adopted, which is the first case at home and abroad. Viewed from the present application situation, such sealing structure has a good effectiveness. |
