摘要
通过对云南安晋高速公路上一座无伸缩缝桥梁进行抗震研究,提出了无缝桥梁的动力建模方法,并对该桥无缝及有无缝两种情况进行抗震计算,得出结论,无缝桥梁较利于抗震。
Through the research on seismic research of a bridge without expansion joint of Yunnan Anjin highway, the paper puts forward the dynamic modlinlg method of seamless bridge, and calculates the aseismicity when there are seams and when there are no seams, and gets the conclusion that the seamless bridge is helpful for the earthquake resistance.
