摘要
国道212线甘肃段是甘肃省南北向的主要通道,在甘肃境内全长707km,公路沿线是我国滑坡、泥石流的主要发育区,特别是陇南市的宕昌—武都段是我国最主要的滑坡、泥石流灾害区之一。线路通过地区的自然地理条件迥异,造成滑坡、泥石流类型和性质有很大差别。本文分析了该区地形地貌时、时空规律性及其与滑坡、泥石流的关系,为未来的高速公路建设提供理论依据。
The section of No. 212 highway in Gansu province is the most important composition of Gansu＇s road network. L, ndslides and debris flows occur very often along this section. The area from Tanchang city to Wudou city is very famous for its active landslides and debris flows. This area is one of the major natural disaster areas in China. The highway goes through different geographical conditions, which causes great difference in styles and characteristics of landslides and debris flows. Based on filed observation and data collected, this paper explores the temporal and spatial variations of geomorphology and the relationship between landforms and landslides and debris flow. It provides guidelines for future design and construction of the highway.
