摘要

方家沟水库是一座采用C15碾压混凝土作为筑坝材料的重力坝,最大坝高41.10 m,坝顶长113.83 m,坝顶高程1 747.10 m。首部枢纽由C15混凝土大坝、坝顶开敞式溢洪道、右岸取水、冲沙底孔及消能设施组成。结合工程特性,对大坝设计方案进行适当优化调整,对其稳定性和应力进行了详细计算。分析结果表明,坝体基本组合情况K'>3.0,特殊组合情况K'>2.5,坝体抗滑稳定满足规范要求,应力计算成果和地基承载力满足规范要求,获得技术上可行、经济上合理的优化设计方案。
        Fang-Jiagou reservoir dam is rolled compaction gravity concrete dam with 41. 1m high,crest length 113. 83 m,and crest elevation 1747. 10 m. The head pivot is consisted with C15 concrete dam,crest open spillway,right bank water intake,sediment discharge bottom outlet and energy dissipation facilities. Combining the project characters and dam architecture shape,the optimum and adjustment design has been proposed,and the dam stability and stress analyzing are carried out. The results show that the dam anti-sliding stability with fundamental combination K' > 3. 0,special combination K' > 2. 5,the dam internal stress and foundation bearing capacity can meet the specification requirements. The optimum design scheme which approved in this paper has high technical feasibility and economic rationality.
