| 摘 要： | 以长沙市潇湘大道北段潇湘嘴-龙王港桥段工程高架桥为研究对象，利用有限元法分析弧形底宽箱梁断面在自重和外荷载作用下的横截面横向效应，分析支承间的横向距离对横向应力的影响，并进行现场测试，可供桥梁结构设计参考。

| Abstract: | Take the viaduct erected between Xiaoxiang mouth and Longwang port as the research object,where is the northern section of Changsha Xiaoxiang Avenue.Through the finite element method,the horizontal effect of the cross-section of wide curved box-girder acted by gravity load and live load is analyzed.The reaction of the horizontal stress responding to the change of horizontal distance between supports is analyzed and discussed either.Field test have been conducted.The conclusion can be refered to in bridge st... |
