摘要
介绍了某半中承式刚性系杆拱桥抗震方案并进行了计算分析比较,结果表明减隔震技术的应用可以有效地改善高烈度区该类桥梁地震作用下的受力状况,并针对大吨位竖向荷载情况运用了分离式减隔震技术,可供类似桥梁设计与分析时参考。
This paper presents the seismic scheme for a half-through tied-arch bridge,and makes calculation and comparison.The results show that the application of separate shaking and shock attenuation technology can effectively improve the stressing state of this type of bridges in areas with high seismic intensity and under the action of earthquake.This technology is also used for large-tonnage vertical load,providing reference for design and analysis of similar bridges.
