大瑞铁路高黎贡山越岭段地质灾害工程分区评价

摘要

In the area where Dali-Ruili Railway crosses the Gaoligong Mountain, the track scheme gets under the geological factors mainly due to the complex geological conditions herein. Through the detailed analysis on the type, scale and influencing factors of geological hazard in this crossing-mountain area, the mathematic model for the engineering division of geological hazard is established by means of analytic hierarchy process, dividing this area into I safety zone, II basic safety zone, III less dangerous zone and IV dangerous zone. The research result is the basis of route selection and design of Dali-Ruili Railway.%大瑞铁路在通过高黎贡山越岭区域时,由于地质条件的复杂性,线路工程方案主要受地质因素控制。通过高黎贡山越岭段地质灾害类型、规模、影响因素的详细分析,采用层次分析法建立了地质灾害工程分区的数学模型,将越岭段地质灾害工程分区划分为Ⅰ安全区,Ⅱ基本安全区,Ⅲ较危险区,Ⅳ危险区四个等级。研究结果为大瑞铁路选线设计提供了依据。
