Study Of Project Feasibility Of The Yellow River Bridge

Proposed the Yellow River bridge project is located in Huimin and Zouping county Binzhou city Shandong province,this bridge is a large highway bridge across the Yellow River after Binzhou Yellow River highway bridge、Binbo super highway Yellow River bridge、Huiqing Yellow River bridge and the Binzhou Yellow River highway-railway bridge, and only a Yellow River super large bridge are directly connected Huimin and Zouping county.The Yellow River bridge engineering passes through Huimin and Zouping county Binzhou city,the starting point is in2kilometers to the west of the Jianglou town, through the national highway G220, To the south and on the Zhaofang village Danianchen town west side of the north shore of the Yellow River dike across the Yellow River, is arrived Guandao village Taizi town Zouping county connected with Tailai road. Route is18.645km, of which the Yellow River bridge is about3779meters long, the main bridge is1000meters long. All go up to four lanes level standards of highway construction, design speed of80km/h, bridge and roadbed width of24.5meters. Across the bridge design vehicle load level are the roads-I level. Scheduled to be completed by the end of2015.The bridge across the Yellow River bridge span3786meters, the bridge standard width of24.5meters, the proposed two separate arrangement, including full width26.5meters, the main to the integral arrangement. Combination (main span1000m span is120+4x190+190m), is proposed to adopt prestressed concrete of short tower cable-stayed bridge, the central cable plane, single-column cable tower, the upper structure adopts prestressed concrete continuous box girder; Bottom structure with thin wall pier, set the ice body into the water, drilling pile foundation. Approach span bridge across the total length of2786meters, of which the cross Yellow River dike bridge upper structure adopts prestressed concrete continuous box girder bridge span length combination (75+140+75m), the lower structure with rectangular pier, drilling pile foundation; DiNa approach using50m/51m cast-in-place continuous box girder and the lower structure USES the vase pier, drilling pile foundation. Dike outside approach of upper with30m prefabricated prestressed concrete box beam, lower part adopts column pier and ribbed plate type abutment, drilling pile foundation. After the completion of the project, will make belong to Binzhou city a river between Huimin and Zouping county to end can only use hd pontoon or borrow road county of history, and the provincial highway S239lines, S242lines with national highway G220, Jinan to dongying highway from south to north along with all the connected, will greatly improve the efficiency of the region road transportation. In addition the project also is the Yellow River delta efficient ecological economic zone development strategy layout and the Jinan city circle of important channel, the implementation of this project to optimize the structure of the provincial backbone network layout, strengthen the Yellow River delta and Jinan city circle, the Shandong peninsula manufacturing industry base and the blue economic zone, the Yellow River delta, Jinan metropolitan circle linkage development, promote the development of the Yellow River delta efficient ecological economic zone development and play a positive role.
