某单跨100m钢箱系杆拱桥总体设计

摘要:

受场地条件限制,常规砼系杆拱桥施工无法搭设支架或吊装作业.钢箱系杆拱桥由于其自身结构重量轻、主梁刚度大,同时具备结构高度低、引桥长度短,总体造价低,在实际工程中使用越来越广泛.本文介绍了某单跨100m下承式钢箱系杆拱桥的总体设计情况,包括结构形式、桥跨布置、断面形式、设计施工要点,对类似工程具有一定参考价值。

Abstract:

SLimited by site conditions, the traditional concreteStiedSarchSbridge can not adequate construction without bracket and hoisting； The steel box tied arch bridge,benefit from its light structure、large rigidity beam、low structure height、short approach bridge length and low overall cost,more and more widely used in practical engineering；This paper introduces the overall design of steel box tied arch bridge with 100 meters’ span,including its structural style、layout of bridge span、section forms and key points of design and construction,has certain reference value for similar projects
