摘要
以松花江大桥工程为例,针对该工程的施工监控,结合该桥所处的地理环境对寒冷地区的混凝土桥梁温度进行现场监测及试验,对寒冷地区的混凝土桥梁结构温度场及温度效应进行研究。在施工监控中采用了立模标高的相对高差形式来消除温度效应的影响。通过对监测与试验数据的分析,得出了一些有意义的结论,并介绍了消除温度对线形控制影响的有效方法。
Based on construction monitoring of the Songhua River Bridge,which is located at cold areas in China,the temperature field and temperature effects are monitored and tested.Relative height difference of formwork erection elevation is adopted to eliminate the influence of temperature effect in construction.Through the analysis of the monitoring and testing data,some significant conclusions are obtained and the effective ways to reduce the influence of temperature on linear control are introduced.
