摘要 首先比较了现行的几种保证连续梁桥顺桥向抗震安全的减隔震措施,然后详细介绍了同济大学桥梁工程系新近开发的双曲面球型减隔震支座的抗震机理和构造特点,接着简要介绍、分析了对该支座进行的抗震性能试验的研究结果,最后通过对一个11跨连续梁桥算例的抗震分析,表明这种减隔震支座非常适用于连续梁桥的减隔震设计. The present condition of China' s seismic design of continuous girder bridges is discussed firstly, and seismic isolation design principle is recommended. The configuration and working mechanism of the double spherical aseismic bearing developed recently are introduced in detail and the seismic performance test results of the bearing are introduced and analyzed briefly. According to a seismic analysis of a continuous girder bridge with eleven spans, this kind of bearing is suitable for the seismic design of continuous girder bridges.
