摘要
采用平面杆系结构模型,实现了金沙洲大桥主桥的施工全过程的计算模拟,重点对混凝土徐变收缩的影响进行了计算分析,并对几个徐变收缩计算模型进行了简略的比较。分析结果表明,正确估算徐变收缩效应有重要的现实意义。同时还介绍了金沙洲大桥施工控制中施工监测的一些情况。
The computation simulation for the whole construction process of the main spans of Jinshazhou Bridge is realized with plane member system structural model. The concrete creep and shrinkage effect of the Bridge is calculated and analyzed, and several computation models of creep and shrinkage are compared in a brief way. The analytical results indicate that correct estimate of the creep and shrinkage effect is of realistic significance. Besides, the construction monitoring during the construction control of the Bridge is described as well.
