摘　　要：以S28灵华高速东延线黑河特大桥为工程依托,针对宽缓河谷地形,从地质、地形角度研究桥位,从地物控制、桥梁高度等因素研究桥梁跨径,进而选择连续刚构、矮塔斜拉桥、斜拉桥等适宜的桥型方案进行比选研究,从设计、施工、造价、景观角度进行对比分析,最终确定黑河特大桥主桥采用矮塔斜拉桥方案。总结了整个方案研究过程,为同类型地形地貌的桥梁方案选择提供参考借鉴。In the paper,taking the Heihe Major Bridge of S28 Lingtai-Huating Expressway East Extension Project as the engineering background,concerning the wide and gentle valley terrain,studies of the bridge site are carried out from the perspectives of geology and topography,and that of the bridge spans layout is carried out from the factors of the ground control and bridge height.Suitable bridge type schemes such as the continuous rigid frame bridge,the extradosed cable-stayed bridge and the cable-stayed bridge are compared and analyzed in terms of design,construction,cost,and landscape.Finally,the extradosed cable-stayed bridge plan is selected for the main bridge of Heihe Major Bridge.The entire study process of the design alternatives is concluded in the paper which is expected to provide some reference for the selection of bridge schemes with similar terrains and landform.
