Conceptual Design And Analysis Of Continuous Rigid Frame Bridge Project For East-Navigable Spans Of Jintang Bridge

Jintang Bridge which is now being constructed is the 5th bridge of Zhoushan Mainland and Islands Link Project. The total length of the Bridge is 20.922 km, in which the part of Bridge over sea is 18.415km. It is the way of land transport links that Zhoushan city to the Yangtze River Delta cities — Shanghai. Hangzhou, Ningbo and other cities. Jintang Bridge construction project will play an important role in promoting integration of Zhoushan Mainland and Islands Link Project, Zhoushan and Ningbo port. The bridge project is a four-lane highway by design, which automobile design speed is 100 km per hour and roadbed width is 26m.This thesis is based on the designing and calculation of the East-navigable spans bridge which is the second largest navigable spans of Jintang bridge. According to the continuous rigid frame bridge design of East navigable spans bridge, It is elaborated from concept design, structural design and structural analysis of the continuous rigid frame bridge, which include detailed calculation processes and the review of the impact of structural design in accordance with the terms of the newly-issued standards by the Ministry of Communications of The people's Republic of China. The last article discuss plans for the bridge construction, and draw series rationalization proposals.The paper, in which stated the technical features of continuous rigid frame bridge, the design dimensions and the processes of analysis for the projects, is hoped to play a certain reference and guidance role for the construction of identical kind of bridges. It would be conductive to deepening the understanding of standards issued by the Ministry of Communications.
