摘要
以某山区高低混合墩连续梁桥为依托,提出了常规抗震措施,设置固定墩,铅芯橡胶支座,液体粘滞阻尼器4种抗震措施。通过4种抗震措施动力特性及动力响应的对比分析得出,对于山区高低混合墩桥梁,设置铅芯橡胶支座或阻尼器抗震效果明显,建议高低混合墩桥梁抗震设计时可优先采用该措施。
Based on the bridge with piers of unequal heights in mountain area,four seismic measures were proposed including general seismic measure, fixed piers,lead rubber bearing and liquidviscous damper. Through comparative analysis of the four seismic measures from dynamic properties anddynamic response,some conclusions were reached. It is an effective measure to set lead supports ordampers for the bridge with piers of unequal heights. In mountain area,the seismic measure is recommended.
