印度比哈尔邦跨恒河主桥是跨越恒河的重要工程。文章介绍了印度比哈尔邦跨恒河主桥的方案构思及设计研究,提出了两种可行的桥式方案,即等高梁矮塔斜拉桥方案、变高梁矮塔斜拉桥方案。在满足结构受力的前提下,以降低工程造价、力求造型美观为原则,对两种桥式方案进行了比选分析,最终选定等高梁矮塔斜拉桥为推荐方案。 The main bridge across the Ganges is the main bridge across the Ganges River in Bihar, India. This paper introduces the concept and design of the main bridge of the Trans-Gan River in Bihar, India. Two feasible bridge schemes are proposed, that is, the scheme of the isopipe dwarf cable-stayed bridge and the scheme of changing the dwarf cable-stayed bridge of the girder. Under the premise of meeting the force of structure, in order to reduce the project cost and strive to make the appearance aesthetically pleasing, the comparison and analysis of the two bridge schemes were carried out.
