摘　　要：湛江海湾大桥主桥是主跨480 m的混合梁斜拉桥。根据设计情况,采用空间有限元法计算分析了其动力特性,并用反应谱法对其抗震性能进行评估,得知其抗震稳定性满足要求。对该桥的抗震措施进行了阐述。The main bridge of Zhanjiang Bay Bridge is a composite cable-stayed bridge with a central span of 480 meters. According to the design information, the dynamic characteristic of this bridge is calculated by three-dimensional FEM, the aseismic capacity according to the theory of earthquake response spectrum is analyzed and the conclusion that its aseismic stability conforms to the professional standards is obtained. In addition, the subject of anti-seismic measures is presented.
