【摘要】 湖北鄂黄长江公路大桥主桥为 55+2 0 0 +480 +2 0 0 +55m的五跨连续预应力混凝土斜拉桥 ,采用双塔双索面全漂浮体系。虽然桥位处抗震设防烈度不高 ,但该桥是跨越长江的特大型桥梁 ,其抗震性能尤为重要。本文结合鄂黄大桥的抗震设计 ,从场址地震安全性评价、地震荷载计算、斜拉桥支撑体系选择、抗震措施等方面研究斜拉桥的抗震性能。更多还原

【Abstract】 E?Huang highway bridge in HuBei is a continuous prestressed concrete cable?stayed bridge of five span, 55+200+480+200+55m. The aseismatic characteristics are very important for this large span bridge, though the seismic intensity on site is not high. The paper presents the researches on the aseismatic features of cable?stayed based on the design of E?Huang bridge from the view of the site seismic safe evaluation, seismic load calculation, support system selection of cable?stayed bridge and aseismatic measures.更多还原
