摘要
新屯水库大坝是一座采用C25W10F100混凝土的面板堆石坝,最大坝高78.5 m,坝基地质条件较复杂,需对坝体结构、布置和基础处理进行深入研究。结合工程地形地质条件,首部枢纽设计由混凝土面板堆石坝、左岸正槽式溢洪道、左岸取水兼泄洪放空系统(导流洞改造)三大部分组成。经多次优化调整后,枢纽布置、大坝经济断面体形、坝基处理等均满足《混凝土面板堆石坝设计规范》(SL 228-2013)对高坝的有关规定,已获得审查批准。
Xintun reservoir dam is C25W10F100 concrete faced rockfill dam with 78.5m high, and the geologic condition of dam foundation is complicated , which need to do the deep research for the dam structure , layout and foundation treatment.Referring to the engineering geological and topo-graphic conditions , the head junction layout consists of the concrete faced rockfill dam , the left bank normal channel spillway , and the left bank water intake and exhaust pipe changed by the diversion tunnel.After doing some optimization and adjustment of the concrete faced rockfill dam , the structure layout , the optimized economical dam section , and the dam foundation treatment can meet the high dam requirements of the 《the design standard of concrete faced rockfill dam》（ SL 228-2013 ） , and has been examined and approved at present.
