摘　　要：长沙至昆明高速铁路穿行于云贵高原,多次跨越河流、水库和深谷。高原山区通道资源有限,高速铁路与既有普通铁路、公路、石油管线等在多个地段选择同一通道,相互交叉时,高速铁路多以桥梁上跨通过。在山区常常出现地面设站困难,而将车站设于桥上。同时本线还穿过9度地震区,桥梁抗震设计需要特殊考虑。桥梁结构设计时充分考虑了上述诸多因素的影响,结合桥梁的功能需求、桥梁所处环境、桥址地形和地质条件,研究设计了多种经济、合理的结构形式,取得了良好的经济和社会效果。本文对长昆高速铁路贵州、云南段桥梁设计进行了总结,介绍了桥梁结构的多样化设计,希望对类似工程设计有所启示。ChangSha-Kun Ming high-speed railway runs through Yunnan-Guizhou Plateau,crosses rivers,reservoirs and ravine many times. The channel resources of plateau mountain area are limited,ordinary railway,high-speed railway,highway and oil pipeline select the same channel. Usually high-speed railways overpass other lines while they intersect.In the mountains it is often difficult to set up ground stations and the station will be located at the bridge. The line also goes through 9 degree earthquake zone,bridge seismic design needs special consideration. Impact of the above factors is fully taken into account when designing bridges. Combined with the functional requirements of the bridge, the environment,topography and geological conditions of bridge site,a variety of economic and reasonable bridge structures are researched and designed,good economic and social effects are achieved. In this paper,bridge design of Guizhou Yunnan Section of Changsha-Kunming high speed railway has been summarized,diversity design of the bridge structure is introduced,it is hoped to have implications for similar projects.
