清水河2号桥为三孔(75 m+120 m+75 m)悬浇刚构公路桥,挂篮设计限重60 t,桥位处风大,最大墩高50 m,工期紧,因此研制三角斜拉挂篮以满足施工需要.这种形式的挂篮结构简单,受力明确,抗风性能强;克服了三角挂篮和斜拉挂篮的不足,通用性强,节省费用明显,具有很好的推广应用前景.
清水河2號橋為三孔(75 m+120 m+75 m)懸澆剛構公路橋,掛籃設計限重60 t,橋位處風大,最大墩高50 m,工期緊,因此研製三角斜拉掛籃以滿足施工需要.這種形式的掛籃結構簡單,受力明確,抗風性能彊;剋服瞭三角掛籃和斜拉掛籃的不足,通用性彊,節省費用明顯,具有很好的推廣應用前景.

No. 2 Bridge on Qingshui River is a three-arch (75+120+75m)cantilever casting road bridge, the construc-tion period of which is short. Weight limit of its basket is 60 T; there is strong wind in the bridge location, with the maxi-mum pier height of 50m. Triangle cable-stayed baskets can meet the requirements of construction, which has a simple structure, definite stress and strong wind resistance. It also overcomes the shortcomings of triangle baskets and cable-stayed baskets, with its versatility and low cost, so it can be promoted in the future.
