摘　　要：以洛河大桥为例,分析了其在施工过程中自重、预应力、收缩徐变、温度梯度等因素对不同曲线半径的高墩大跨曲线连续刚构桥横向变位的影响,以大大改善道路系统的整体运输性能。Taking Luohe Bridge as an example, this paper analyzes the influences of self-weight, pre-stress, shrinkage and creep, and temperature gradient on transverse deflection of high-pier large-span curved continuous rigid frame bridges with different curve radius in the construction, in order to ameliorate entire transport performance of road system.

关 键 词：曲线桥 预应力 横向位移
