河头上水库混凝土面板堆石坝枢纽布置及结构计算
|
摘要
针对河头上水库坝址区地质条件较复杂,岩体表层裂隙发育、岩体破碎和软弱夹层等地质缺陷,存在岩体完整性较差、岩溶渗漏、楔形体滑塌和边坡开挖稳定性差等不利地质问题,结合地质勘探揭露成果,围绕坝型地形地质适应性、枢纽布置合理性、坝基防渗处理和节省投资等关键技术问题进行研究。结果表明:优选的混凝土面板堆石坝坝型,其地形地质适应性强、施工技术成熟、工期较短,具有良好的技术可行性和经济优越性,可为工程顺利施工建设提供重要技术保障。
The complex conditions of topography and geological with fracture development at rock surface,rock mass broken,and weak interlayer defect which will cause unfavorable geological problems such as poor rock mass integrity,karst seepage,wedge collapse and poor stability of slope excavation has been introduced in Hetoushang reservoir.Combining site reconnaissance,the deep research for geological adaptability of dam type,rationality of hub layout,anti-seepage treatment of dam foundation,investment saving and other key technical issues has been done.The analyzing results show that the optimal schemes of concrete face rock-fill dam with strong topographical geological adaptability,mature construction technology and short construction period has good technical feasibility and economic superiority,which can provide important technical support for smooth construction.
