本文通过对某高烈度地震区高速公路大跨径桥梁的不同桥型方案进行非线性时程抗震分析,并进行减隔震设计。研究结果表明,在高烈度地震区桥型方案的选择具有至关重要的作用,连续梁桥方案较刚构梁桥方案具有更为优越的抗震性能。 In this paper, the non-linear time-history seismic analysis of different bridge types of long-span bridges on highway in a high-intensity earthquake area is carried out and the seismic isolation design is adopted. The results show that the selection of the bridge scheme is of crucial importance in the seismic zone with high seismic intensity, and the continuous beam bridge scheme has more superior seismic performance than the rigid beam bridge scheme.
