香山水库位于大别山北麓的河南省新县县城东南6km处、淮河水系潢河一级支流田铺河上,控制流域面积72.80km2,防洪标准为100年一遇洪水设计,1000年一遇洪水校核,总库容8385万m3,是一座以防洪、城市供水、发电为主,结合灌溉、水产等综合利用的中型水库。由于其位置重要,水库被省水利厅列为全省25座重点中型水库之一,按大型水库进行管理。文章介绍了香山水库拱坝基本情况和除险加固方案,并对砌石拱坝除险加固前后多种工况的应力和坝体抗滑稳定进行计算分析,从结构安全角度论证了除险加固效果,进行了有益的探索。
Xiangshan Reservoir is located 6km southeast of Xinxian County, the northern foot of the Dabie Mountains. The Huaihe River basin is a tributary of the tributary of the Huanghe River. The control basin covers an area of 72.80km2. The flood control standard is 100-year flood design and 1000 flood check With a total capacity of 83.85 million m3. It is a medium-sized reservoir that integrates flood control, urban water supply and power generation with irrigation and aquatic products. Due to its important position, the reservoir has been listed as one of the 25 key medium-sized reservoirs in the province by the provincial water conservancy department and managed by a large reservoir. This paper introduces the basic situation of Xiangshan Reservoir Arch Dam and the program of reinforcement and reinforcement, and calculates and analyzes the stress of various conditions before and after masonry arch dam reinforcement and the stability of the dam body, and demonstrates the advantages of reinforcement and reinforcement Effect, conducted a useful exploration.
