| 摘 要： | 运宝黄河大桥主桥为(110+2X 200+110) m波形钢腹板低塔斜拉桥,副桥为(48+9X 90+48) m波形钢腹板刚构一连续组合体系桥。主桥主梁为整体式单箱五室截面,腹板采用波形钢腹板—混凝土腹板混合形式(中间2道为混凝土腹板,其余4道为波形钢腹板),中间箱室采用混凝土横隔板,两侧箱室采用钢横隔板;副桥主梁为分幅式单箱单室截面,腹板采用波形钢腹板;波形钢腹板与混凝土顶板采用双开孔板连接件连接,主桥中腹板与混凝土底板采用焊接角钢的翼缘型结合部,主副桥边腹板与混凝土底板采用外包型结合部,可提高结合部耐久性;波形钢腹板采用耐候钢,无需进行防腐涂装,节省后期维修养护成本。主桥采用挂篮悬臂浇筑施工,副桥采用钢腹板自承重架设工法,提高了施工效率和安全性。
