摘　　要：在建的沪昆高速客运专线贵州东段在线路方案确定时期,通过对线路引入既有凯里站整治站内插旗山古滑坡方案和绕行新建车站方案的比较,以确定线路区域走向,选择出最优线路方案。从工程地质状况、病害整治条件、设站条件、工程数量及造价、地方发展规划等方面比较,结合高速铁路技术特点和安全要求,对影响方案重要因素的插旗山古滑坡目前的稳定情况、既有的工程状况、整治工程规模及工程安全等进行分析研究。围绕该滑坡的整治与绕避进行了较大范围的方案比较,为线路方案的决策提供了可靠的技术依据,通过方案研究,最终选择了绕避插旗山古滑坡采用新建凯里南站的线路方案。When determining the line scheme of Guizhou east section of Shanghai-Kunming high-speed passenger dedica-ted line under-construction, two schemes of the line led into the existing Kaili station were taken into comparison to de-termine the regional alignment of the line and choose the best line scheme, one is to renovate Chaqi mountain ancient landslide, the other is to detour and build the new railway station. By comparison of such aspects as the engineering geo-logical conditions, disease control condition, station setting conditions, engineering quantity and cost as well as the re-gional development planning, and combining with the characteristics of high speed railway technology and safety require-ments, the key factors which affect the scheme most like the present stability of Chaqi mountain ancient landslides, the existing engineering condition, the engineering scale and engineering safety are analyzed. The scheme comparisons be-tween treatment and detour of the landslide are performed in a large range, which provides a reliable technical basis for the scheme selection. Under the deep discussion, the line scheme of detouring from Chaqi mountain and building the new KaiLi south railway station is chosen.
