长江重要堤防隐蔽工程建设综述

Summary on construction of concealed works for important dykes along the Yangtze river

长江重要堤防隐蔽工程包括护岸及河段整治、堤身堤基防渗处理、大型穿堤建筑物除险加固等。工程建设项目分布广、战线长 ,各项目的堤基结构和堤身状况、穿堤建筑物状况、河势变化情况、水文及地质条件均不尽相同 ,工程结构型式和施工技术要求也不相同 ,工程技术问题复杂 ,施工难度大。针对各施工项目的建设特点和难点 ,采取合理的施工方法和技术及管理措施 ,切实保证工程建设质量 ,提高工程技术水平和投资效益 ,是工程建设管理中的重点。

The concealed works of important dykes along the Yangtze river include bank revetment, river regulation, seepage prevention of dyke body and foundation, removing hidden danger for large structures passing through dyke etc. The dyke works distribute widely along the Yangtze river and are in different condition of dyke foundation structure and dyke body, dyke passing structure, river regime, hydrologic and geologic condition. The works are also different in structure type and construction requirements, complicated in engineering technology and difficult in construction. In the light of the construction features and difficult points of various works. The main attention in construction and management of works should be paid to adopting reasonable construction method and technology and management measures to guarantee construction quality and upgrading engineering technology and investment benefit.
