| 摘 要： | 以主跨为160m的波形钢腹板和预应力混凝土桥为研究对象,通过数据模拟分析,比较了2种结构的预应力效应、温度梯度、温度变化、成桥状态下的应力分布和徐变收缩等影响.计算结果表明:与预应力混凝土桥相比,波形钢腹板桥的预应力效率高,但徐变收缩导致的预应力损失大,受温度影响略小.

| Abstract: | The corrugated steel web structures with a span of 160 meters and prestressed concrete bridge were studied.By analyzing the simulation data,the prestressing effect,temperature gradient,temperature changing,stress distribution under the finished bridge status and shrinkage and creep of the structure between the two different structures were compare.According to the results,the corrugated steel webs bridge had higher efficiency of prestressing than prestressed concrete bridge;on the other hand,corrugated steel webs bridge's prestress suffered more;the temperature exerted little influence on it. |

| Keywords: | corrugated steel webs continuous rigid frame bridge prestressing effect static characteristic |
