| 摘 要： | 随着我国高速公路建设不断向西部山区发展，面临的崩塌、滑坡、泥石流等不良地质问题日益突出，迫切需要在选线阶段利用新的技术手段对拟建高速公路沿线不良地质体进行早期识别。以西昌—香格里拉拟建高速公路廊道为研究区，利用“天-空-地”一体化综合遥感手段，识别出不良地质体174处，其中滑坡74处、崩塌40处、泥石流16处、堆积体44处，利用小基线集合成孔径雷达干涉测量技术探测到26处不良地质体具有形变信号。针对磨盘山隧道—雅砻江桥段、牦牛山隧道出口段和下麦地隧道出口段不良地质体发育密集、规模大、稳定性差、对拟建线路威胁极大的区段，项目组开展了详细调查和分析评价。研究结果为西香高速线路比选和后期详细勘查提供了支撑，也为线路工程的不良地质体调查评价提供参考。

| Abstract: | With the development of expressway construction towards the western mountainous areas in China, the adverse geological problems such as collapse, landslide and debris flow are becoming increasingly serious. It is urgent to use new technical means to identify the adverse geological bodies along the proposed expressway in the early stage of route selection. the article applied the integrated remote sensing method of " Space-Air-Ground " to identified 174 adverse geological bodies, including 74 landslides, 40 collapses, 16 debris flows and 44 deposits along the proposed Xichang-shangri-La expressway. Applied small baseline subsets interferometric synthetic aperture radar technique to detected 26 adverse geological bodies with deformation information. This article have carried out a detailed investigation and comprehensive evaluation on the section of Mopanshan tunnel - Yalong River bridge, the exit of Maoniushan tunnel, the exit of Xiamaidi tunnel where adverse geological bodies are densely developed, large in scale and poor in stability, posing great threat to the proposed line . The results provide support for routes comparison and later investigation of Xichang-Shangri-La expressway. It also provides reference for the investigation and estimate of adverse geological bodies along line engineering. |
