摘　　要：珠海洪鹤大桥辅航道桥采用85m+2×160m+85m四跨预应力混凝土连续刚构,主梁为单箱单室变截面混凝土箱梁,主桥桥墩采用双肢变截面矩形实心薄壁墩。由于该桥位于高地震区,依据抗震设计原则初步拟定桥梁结构尺寸,并采用有限单元法对大桥进行静力计算和抗震计算。结果表明,该桥的各项指标均满足规范要求。The assistant shipping channel bridge for Zhuhai Honghe Bridge is a four-span prestressed concrete continuous rigid frame bridge with span arrangement（85 ＋2×160 ＋85）m.The beam is a concrete single cell box girder with varied section,and the piers of the bridge are designed as two-leg rectangular thin-wall solid piers with varied sections.The bridge is located in active seismic region,based on the seismic design principles,the dimension of the structure is initially determined.The static and seismic analysis of the structure is calculated using the finite element method.The results show that all indices of the bridge can meet the requirements in the codes.
