摘要
跨中下挠过大是目前国内大跨径连续刚构桥的主要病害之一.对跨中下挠过大的原因进行了全面的分析,并在此基础上提出了有效的改进措施.
The excessive deflection in the midspan is one of the main faults in long-span continuous rigid frame bridges . This paper make a comprehensive analysis for the causes of the excessive deflection and find out the countermeasures for this problem.
