沪昆客运专线玉屏至昆明段地质选线研究

Research on Geological Route Selection of Yuping-Kunming Section on Shanghai-Kunming Passenger Dedicated Line

在西南艰险山区修建铁路,不仅要克服地形条件上的困难,还得面对复杂的不良地质环境。文章对沪昆客运专线玉屏至昆明段的煤层瓦斯及采空区、深厚层软土以及岩溶发育等重大不良地质的选线研究进行了详细论述,并在此基础上总结出在线路选线中处理煤层瓦斯及采空区、软土、岩溶等重大不良地质的思路和原则。

To build railways in complex dangerous southwest mountainous areas, we have to get over the topographic dif- ficulties, and deal with unfavorable geological phenomena. The article discuses the route selection in unfavorable geology circumstances in detail, which includes coal seams gas, abandoned workings, deep soft soil, strongly developed karsts distributed in the Yuping-Kunming section of Shanghai-Kunming passenger dedicated line. Thought and principle of route selection in unfavorable geologic areas with above mentioned difficulties are summarized based on the discussion.
