对地质学家而言,川藏公路素有地质博物馆的美称,沿线地形、地貌和地质现象的复杂性和多样性堪称世界之最。同样,由于地形、地貌、地层条件及气候的复杂性和多变性,川藏公路沿线的地质灾害也表现出不同寻常的特殊性、复杂性。每年雨季,川藏公路沿线大大小小的滑坡、崩塌、泥石流、落石等地质灾害频频发生,造成极为严重的经济损失和社会影响,制约西藏地区的经济发展,影响社会稳定。以著名的102滑坡群为例,该滑坡地区为一地形复杂、地层复
For geologists, the Sichuan-Tibet Highway is renowned for its geological museums. The complexity and variety of topography, geomorphology and geological phenomena along the route are among the highest in the world. Similarly, due to the complexity and variability of topography, geomorphology, formation conditions and climate, geological disasters along the Sichuan-Tibet Highway have also shown unusual specialities and complexities. Every year during the rainy season, large and small landslides along the Sichuan-Tibet Highway, landslides, debris flows, rockfalls and other geological disasters occur frequently, causing extremely serious economic losses and social impacts, restricting the economic development in Tibet and affecting social stability. Take the well-known 102 landslide group as an example, this landslide area is a complicated topography and complex strata
