    中巴公路盖孜河段水毁类型与防治工程优化设计

    TYPES OF WATER DAMAGE AND OPTIMAL DESIGN OF PREVENTION MEASURES ALONG GAIZI SECTION OF SINO-PAKISTAN HIGHWAY

    • 摘要: 中巴公路盖孜河段水毁灾害频发且危害严重, 文章在实地调查的基础上, 对沿线水毁灾害进行成因分析和典型防护工程优化方案设计, 从而达到控制水毁灾害的效果。实地调查发现, 盖孜河段公路水毁工点共计18处, 类型多样且呈段落性分布; 宽谷段和窄谷段发生水毁的工点共计13处, 峡谷河段为5处。结果表明:工点水毁的形成和发展受盖孜河水文和地形条件共同控制, 其中水动力条件为最主要控制要素, 河谷地形控制水毁的分布特征与破坏形式, 水文和地形条件的共同作用促成了当前盖孜河段水毁工点分布现状。通过水工模型试验验证了当前水毁特征和防护结构水毁存在的问题, 文章基于对实地水毁灾害特点和防治工程存在的问题进行分析, 因地制宜开展水毁优化设计, 提出典型水毁防治工程优化设计方案, 实践证明在工程后期运行中防护效果较好。

       

      Abstract: As for the fact that the frequent and serious water damage disasters in the Gaizi River section of Sino-Pakistan Highway, we performed analysis and optimization design research for the actual road waterlogging disasters. In investigation, we found there was a total number of 18 water damaged work sites in the Gaizi river section. The work sites had various types and they were segmental distributed. The result shows that the hydrology and topographic conditions of the Gaizi River control the occurrence and development of water damage at the worksite. The hydrodynamic conditions are the most important control elements of water damage on roads. The valley terrain controls the distribution characteristics and the destructive form of water damage. The combined effect of hydrology and topographic conditions contributed to the current distribution of water destroyed worksites in the Gaizi river section. After verifying the current water damage characteristics and the water damage problems by hydraulic model test, we analysed the characteristics in real water damage disasters and the problems existing in the prevention and control project in paper. We proposed the optimal design scheme of typical water damage prevention and control project from the perspective of technical scheme adjustment and economic rationality. Finally, it was found that the protection effect was better in the later operation.
