摘要
以上海地铁二号线东延伸段高架区间的预应力简支梁为研究对象,对预应力简支梁在各阶段预拱度和后期徐变进行跟踪监测。根据监测数据,分析了预应力简支梁预拱度和徐变的分布规律及其影响因素,得出一些对预应力简支梁预拱度大小设计有参考价值的结论。
Precamber and creep of prestressed simple beams in eastern extension viaduct section of Metro Line 2 in Shanghai were monitored. Based on the monitoring data, the distributions and influencing fac tors of the precamber and creep were analyzed. Results of the analysis should serve as valuable references for the design of precamber of prestressed simple beams.
