| 摘 要： | 高性能混凝土的早期收缩是引起连续刚构桥早期裂缝的一个重要方面，而知道早期裂缝主要发生在桥梁截面的那个位置对桥梁的施工具有一定的指导作用．根据当量温差的计算方法，通过AN—SYS软件对其进行有限元分析，然后与监控的实验数据进行比较、分析．结果表明，利用当量温差理论对混凝土构件的早期收缩进行分析比较合理，对桥梁因早期收缩产...

| Abstract: | The early contracting of high-performance concrete is an important aspect of the early cracks of continuous rigid frame,and knowing the early cracks occurring in the position of the bridge section plays a certain direct role in the bridge construction.Based on the equivalent temperature calculation method,this paper gives the finite element analysis through ANSYS software,and then conducts comparison and analysis on the monitoring experimental data.Results shows that the early shrinkage analysis is relative... |
