| 摘 要： | 根据1999年春季对松花江公路大桥3号桥墩动冰压力实测得到的两条完整河冰动压力时程曲线，采用有限元方法计算分析了松花江公路大桥在静、动流冰压力作用下的位移响应，并与按现行公路桥涵设计规范方法进行计算的结果作了比较，表明流冰对粗壮钢筋混凝土实体重力式桥墩的位移响应很小，一般可不考虑动冰压力引起的振动效应。

| Abstract: | Based on the two completed time-history ice pressure curves obtained on the 3rd pier of Songhua River Highway Bridge in Spring 1999, the displacement response of Songhua River Highway Bridge under both static and dynamic ice pressures was analysed using the finite element analysis method and compared what is specified in with the current Road Bridge & Culvert Design Specifications'. The results of comparison show that the displacement response of thick and solid reinforced concrete pier under the dynamic ice pressure is very small and the vibration effect of moving ice sheet in common bridge structure design in cold region can be neglected. |
