| 摘 要： | 广东韩江特大桥为超长多跨连续梁桥,场址地震烈度较高,抗震设计对结构体系方案的影响较大。从抗震设计的角度对韩江特大桥的结构体系设计进行了比选,对双曲面球型减隔震支座的减震效果进行了计算分析,并介绍了速度锁定器支座的应用,以期为同类桥梁的减隔震设计提供借鉴。

| Abstract: | Hanjiang Bridge in Guangdong Province is a super-long multi-span continuous girder bridge,which is located in a site of high seismic intensity,hence the seismic design has great impact on the structural system design.In this paper,the structural system design of Hanjiang Bridge has been deeply studied and compared on the basis of structural stress,the damping effect of double spherical aseismic bearing has been calculated and analyzed,the application of lock-up bearing has been introduced,with the hope that useful reference could be provided for the seismic isolation design of future similar bridges. |
