预应力混凝土连续箱梁桥试验研究及病害分析

Monitor and analysis of the defects in the prestressed box-girder of bridge

通过一座预应力混凝土连续桥的现场检测 ,应用有限元法对该桥的箱梁进行了分析 ,得出影响箱梁病害的主要原因 ,并提出了预防措施。

This paper deals with a three span continuous box-girder. Monitoring the bridge, the reason for the defect of the bridge is analyzed. By means of finite element and the engineering case, the major measures to treat the defect of the bridge are given.
