弧形闸门的支承铰布置在闸墩体外的牛腿上,其受到弯、剪、扭力的作用,在设计、施工中采取必要的处理措施。文章着重介绍闸墩体外牛腿的结构计算和施工冷缝的处理方法,并提出其计算、施工处理时应注意的问题。 The support of the arc gate is arranged on the cow leg outside the gate pier, which is subjected to the functions of bending, shearing and torsion, and taking the necessary measures in the design and construction. This article focuses on the structure calculation of the pier outside the gate pier and the construction of the cold seam processing methods, and put forward its calculation, construction treatment should pay attention to the problem.
