Engineering Geological Division of Geological Hazards along Dali-Ruili Railway in Gaoligong Mountain Section

    摘要
  • 摘要: 为了有效评判崩塌、滑坡、泥石流等地质灾害对大瑞铁路工程的影响,针对高黎贡山越岭段地形地貌复杂、岩土体类型多样、活动断裂频繁发生的特点,在进行现场调查和分析工程勘探资料的基础上,考虑地质灾害发育程度及工程风险因素,将工程地质灾害危险性划分为安全、基本安全、较危险和危险4个等级,用层次分析法建立了工程地质灾害危险性分区模型,并将该模型用于线路区域工程地质灾害的分区评价.研究结果表明,小寨子—芒市段的工程地质灾害等级为基本安全和较危险,当前线路方案有效规避了地质灾害对线路工程的影响.

     

    Abstract: The Gaoligong Mountain section of Dali-Ruili railway line is characterized by complicated topography and terrain, diverse rock and soil mass, and frequently active faults. In order to evaluate the impact of geological hazards such as rock falls, landslides, and debris flows on the railway project in this section, a field investigation was made into the geological materials to analyze the development of geological hazards and engineering risks. The grades of geological hazards were divided into four grades: (Ⅰ) safe, (Ⅱ) moderately safe, (Ⅲ) relatively dangerous and (Ⅳ) dangerous. Using the analytic hierarchy process (AHP) theory, a evaluation model was then established, and used for engineering division of this section of railway line, by evaluating the risk of the geological hazards. The results show that the grades belong to Ⅱ and Ⅲ from Xiaozhaizi to Mangshi, and the present route plan can avoid the impact of dangerous geological hazards.
