中春路(莘庄镇至淀浦河)高架桥梁设计浅述

由于中春路跨越莘庄镇区、沪杭高速公路及淀浦河段,因此如何选择桥位及桥梁方案以满足交通和桥梁结构受力、景观要求、减少工程造价就显得尤为重要。通过调研协商及多方案比选,合理选定了跨越莘庄镇、沪杭高速公路、淀浦河的高架桥梁方案以及跨越淀浦河东闸段桥梁的桥位及半中承式双肋系杆拱桥方案。

On Design of Zhongchun Rd (Xinzhuang-Dianpu River) Elevated Bridge

As Zhongchun Rd lays across Xinzhuang Town,Huhang Freeway and the Dianpu River,it is extremely important for the selection of bridge location and draft design of bridge to meet the requirements of traffic,bridge structural loading,aesthetics,and the economizing of construction cost.Based on study,investigation,and comparison of multi-options,an appropriate decision is made to choose the design draft of elevated bridge over-crossing the Xinzhuang Town,Huhang Freeway and the Dianpu River,as well as the location of bridge over-crossing the vehicle-brake section of Dianpu River,and the design draft of a semi-half-through double rib tied arch bridge.
