摘要
主要介绍了苏通大桥辅桥(140m+268m+140m的预应力混凝土连续刚构桥)主梁高性能混凝土的收缩徐变试验,并将部分试验结果与现有的几种收缩徐变模式进行了比较,试验结果将为苏通辅桥以及其它连续刚构桥的施工位移监测提供有益的依据。
The experiment on creep and shrinkage of high-performance concrete used in Sutong auxiliary bridge which is a three span prestressed concrete continuous rigid-frame box girder bridge (140 m+268 m+140 m)with single cell is introduced. Six commonly-used prediction models for concrete shrinkage and creep are compared with some experimental results. It can provide necessary analytical parameters for the construction.
