新屯水库大坝是一座采用C25W10 F100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。
新屯水庫大壩是一座採用C25W10 F100混凝土的麵闆堆石壩，最大壩高78.5 m，壩基地質條件較複雜，需對壩體結構、佈置和基礎處理進行深入研究。結閤工程地形地質條件，首部樞紐設計由混凝土麵闆堆石壩、左岸正槽式溢洪道、左岸取水兼洩洪放空繫統（導流洞改造）三大部分組成。經多次優化調整後，樞紐佈置、大壩經濟斷麵體形、壩基處理等均滿足《混凝土麵闆堆石壩設計規範》（ SL 228-2013）對高壩的有關規定，已穫得審查批準。

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.
