摘要
务川县城地处洪渡河中游左岸台地,区域水资源丰富。由于洪渡河河谷深切,低于县城地面,水资源难以利用。为满足务川县经济社会发展需要,规划建设冉渡滩水库。针对洪渡河流域特征,研究计算坝址处设计径流与洪水成果,分析库区和坝址处地质条件及存在问题,确定了碾压混凝土重力坝为推荐坝型。对冉渡滩水库的规模与工程总体布置进行了详细论述,特别是对挡水和泄流等关键建筑物主要设计参数进行了计算,以期为类似工程设计提供借鉴。
Wuchuan County is located on the platform on the left bank of the middle reaches of the Hongdu River.This area is rich in water resources.Due to the deep valley of the Hongdu River,which is lower than the county ground,water resources are difficult to use.In order to meet the needs of the economic and social development of Wuchuan County,Randutan Reservoir is planned to be built.According to the characteristics of the Hongdu River Basin,this paper studies and calculates the design runoff and flood results at the dam site,analyzes the geological conditions and existing problems at the reservoir area and the dam site,determines the RCC gravity dam as the recommended dam type,and discusses in detail the scale and general layout of the Randutan Reservoir,especially calculates the main design parameters of key buildings such as water retaining and discharge,in order to provide reference for similar project design.
