合肥市集贤路跨派河大桥主桥总体设计

Overall Design of Main Bridge for Paihe River Bridge in Jixian Road of Hefei City

摘要:

合肥市集贤路跨派河大桥主桥是主跨132 m的钢桁拱-箱形梁混合结构桥梁，桥梁边跨至梁端24 m采用了分离式钢箱梁与钢桁拱连接。阐述该主桥总体设计时在主桁型式、片数、矢跨比等方面的方案比选及确定，以及吊杆、桥面板等结构构造设计细节。该桥的建成对同类型桥梁的设计提供了工程借鉴案例。

Abstract:

The main bridge for Paihe River Bridge in Jixian Road of Hefei City is a steel truss arch - box beam composite structural bridge with 132-m main span. The separated steel box beam and steel truss arch are used to connect the bridge 24 m from the side pier to beam end. The scheme comparison and determination of the main truss type, number and rise span ratio as well as structural design details of suspender and deck slab in the overall design of this main bridge are expounded. The construction and completion of this bridge provide an engineering reference case for the design of the similar bridges.
