输电线路装配式承台锚杆基础形式研究

Research on the Foundation Form of Assembly Cushion Cap Anchor Rod of Transmission Line

针对山区岩石锚杆基础和装配式基础存在的使用性不足,发挥输电线路锚杆基础和装配基础各自适于不同的输电线路建设要求的特点,原创性的将装配式基础与锚杆基础联合,形成新的装配式承台锚杆基础。装配式承台锚杆基础不但能充分利于岩石自身的抗剪切性能,很好地抵抗外部载荷,节约材料量,减小了土石方量,满足工程建设的环境保护要求,同时承台实现了装配化、工厂化、标准化,使输电线路原状土基础实现装配化、机械化施工。本文研究了该基础在山区线路工程中应用的可能性,提出了几种装配式基础形式,分析了设计计算方法和经济性。为山地输电线路基础设计提供了一种全新的基础形式,具有较强的推广和应用价值。

In mountain area,in view of the defects and shortages of rock anchor rod foundation and assembly foundation,give play to characteristics that the anchor rod foundation and the assembly foundation of the transmission line,they are adapt to different transmission line construction,originality combination of the assembly foundation and the anchor rod foundation,form the new assembly cushion cap anchored rod foundation.The assembly anchored rod foundation not only take advantage of anti-shear ability of rock,resist the external load,save material,reduce the amount of earth-rock,meet the environmental protection requirements of engineering construction,but also realize foundation construction of the transmission line Assembly,factory-like,standardization and mechanization.In this paper,research the possibility that the new assembly cushion cap anchored rod foundation used in mountain area transmission line construction,bring up several kinds of assembly foundation formsy,and analyze the calculation method and economy.It provides a new foundation form for design of the mountain transmission line,and has a strong popularization and application value.
