EXPERIMENTAL RESEARCH OF VEHICLE-BRIDGE COUPLING VIBRATION OF DOUBLE ARCH BRIDGE

摘要：

The influence of dynamic performance of Double Arch Bridge about gross rail load on axle and speed has not been studied. Combined an old double arch bridge, author has carried out an experiment of vehicle-bridge coupling vibration.From the experiment, the correlation between dynamic coefficient and speed, the correlation between impact coefficient and speed as well as the rules of bridge vibration have been found. After the experiment, through the analysis of parameters, author has carried out a vehicle-bridge coupling vibration of naked arch in theory and put forward some conclusions, that can provide references to reinforcement design of double arch bridge for some engineers.
