基于病害检测的连续刚构桥震害预测方法研究

在连续刚构桥的运营过程中,桥梁各部件可能出现锈蚀、变形、腐蚀、开裂等多种病害,这些病害可以使桥梁各部件的功能退化甚至消失,使它们达不到设计时的抗震要求,严重影响其抗震性能。在对连续刚构桥的构造特点及病害加以分析的基础上,研究了连续刚构桥病害对其抗震性能影响的评价,并用扣分的形式加以表现。

The method for earthquake damage prediction of continuous rigid frame bridge based on the disease detection

In the operation process of continuous rigid frame bridge, Bridge components possible corrosion, deformation, cracking, corrosion and other diseases, these diseases can make the parts of bridge function degradation or even disappear, so that, they are not up to the design of the seismic requirements, seriously affecting the seismic performance of continuous rigid frame bridge, This paper based on the structural characteristics and diseases of the continuous rigid frame bridge to be on the basis of the analysis, study continuous rigid frame bridge disease on the seismic performance evaluation, and points that the form of expression.
