枢纽小半径斜弯坡桥梁设计问题研究

摘要

以吉县至河津高速公路吉县枢纽桥梁设计为例，从桥梁设计的总体思路、现浇桥梁的横隔板设置、桥梁支座的预偏心设计以及桥面板的受力分析等不同角度对目前互通枢纽内的小半径斜弯坡桥梁进行了设计问题研究，同时也探讨了该类桥梁设计中应注意的一些问题及预防措施，以确保桥梁设计合理、可靠。%Taking the design of terminal bridge on Ji county-Hejin highway as an example, this paper studies the terminal inclined slope bridge design with small radius from aspects of overall bridge design idea, diaphragm plates setting of east-in-situ bridge, predicted eccentric design of the bridge support and the bridge deck stress analysis and so on, and simultaneously explores matters needing attention in similar bridge design and protective measures, so as to ensures the rationality and reliability of the bridge design.
