介绍了弧形闸门支承结构的预应力补强加固方法.根据弧门推力和结构内力,平行弧门推力方向布置钢绞线,锚固端埋入闸墩七游内部,对支座施加的作用力与弧门推力方向相反,以抵消部分推力.这种方法概念清晰,受力明确,不破坏原结构的整体性,施工快捷简便,应用前景广阔.

This paper introduced the pre-stressing reinforcement method for supporting structure of the radial gate. According to thrust power of the radial gate and internal force of the structure,the steel strands were arranged to be parallel with the gate thrust,with the anchored end embedded in the upper part of the pier. Thus,the applied force to the bearer was opposite to the thrust of the radial gate, decreasing the thrust partly. This method, with clear concept, specific force analysis, doesn't exert influence on integrity of the structure and was convenient for fast construction. So, it should have extensive application in reinforcement field.
