摘要
以混凝土系杆拱桥的检测为例,阐述了混凝土桥梁可能出现的病害问题,桥梁安全性评估理论、桥梁需要检测的内容以及具体的检测方法。利用测得实际数据资料对桥梁的承载能力进行有限元计算分析,评估现役桥梁的整体工作性能。通过不同工况下的静载试验,结合动力测试,测得其频率,分析了车辆对其的冲击系数。根据相关规范,结合全桥检测资料,给出桥梁评级。
Taking the check on arch bridge with concrete fastening bar as example,the paper expounds the diseases may presented within such bridge,evaluation for bridge safety and check method. Then using the tested information,with the finite element method,analyses the load capacity of bridge. Combining with dynamic test,we get its vibration frequency,and analyze the shock coefficient by vehicles. Finally according to relevant norm,evaluate the safety degree.
