摘要
结合工程实例,进行了25m和30m预应力混凝土预制T梁在存梁期间上拱挠度影响因素(反拱度、预应力损失、徐变,温度)的分析,并提出了控制梁体上拱挠度的措施。研究结果可对类似工程提供借鉴。
Factorial analysis for camber of T shape precast beam with 25m and 30m span in resting period was carried out. Influence factors include inverted camber, prestressing loss, creep and temperature. The method to control camber of beam was presented. Research results could be draw lessons from other similarly project.
