摘要
以洛河大桥工程为背景,研究了高墩大跨连续刚构桥在风荷载和地震荷载作用下的桥梁动力反应。通过风洞试验对该桥风荷载作用下测压,测振试验以及计算地震力作用下的时程分析进一步明确该桥的实际受力状况。
With reference to Luohe River Bridge Project, this paper conducts a study of dynamic response of long span continuous rigid-frame bridge with high-rise piers subjected to wind load and seismic load, and makes definite in a further way the actual mechanical conditions of the type of the bridge on the basis of measurement of wind pressure and vibration on the bridge by wind tunnel tests, and through analysis of time history of the response under calculated seismic load.
