嘉兴至南北湖(海盐段)公路于城桥结构稳定性分析

Structural Stability Analysis of Yucheng Bridge on Jiaxing-Nanbeihu(Haiyan Section) Highway

于城桥位于嘉兴至南北湖(海盐段)公路于城集镇处,通过详细介绍该桥的工程概况、结构型式、计算依据、材料参数、计算荷载及工况划分等,对施工阶段和运营阶段进行稳定性分析,证明该桥不会发生纵向失稳。这一计算分析可为类似工程提供参考与借鉴。

Yucheng Bridge is located in Yucheng Market Town of Jiaxing-Nanbeihu （Haiyan section） Highway. By introducing the general situation,structural style,calculation basis,material para-meters,calculated load,operating mode division and other condition of the bridge in detail,the stability of bridge in construction phase and operation phase is analyzed,which proves that the bridge will not have longitudinal instability.
