摘要
通过对某大桥体系转换加固,结构的荷载作用效应降低,等同于间接提高了结构的承载能力,加固后的荷载等级达到了汽—15、挂—80,经近两年的运营表明加固效果良好。
Through the reinforcement on some bridge system transformation,the load effect of the structure is reduced,which means the structural carrying capacity is improved indirectly.After the reinforcement,the load grade reaches automobile-15 and trailer-80.After two years＇ operation,a good reinforcement result is gained.
