摘要
新藏公路 (新疆境内 )地处昆仑山中、西段 ,沿线道路病害类型多样 ,有泥石流、滑坡、水毁、崩塌、雪害、涎流冰、翻浆、冻土等 ,严重威胁和破坏交通。由于所处地域自然环境条件特殊 ,病害频频发生 ,随着全球气候变暖 ,冰川退缩 ,病害将愈演愈烈。本文在实地调查的基础上 ,分析了研究区病害发育现状、分布规律、成因以及发展趋势 。
Xinjiang-Tibet Highway in Xinjiang is located in the west and middle section of Mt.Kunlun.Debris flow, water erosion, landslide, snow drift, snow avalanche, permafrost, etc., develop expansively along the line and cause tremendous disasters to highway construction, because of the complicated characteristics of geomorphology, geology, tectonic movements, climate, and hydrology.There are 291 disaster points, including 149 debris flow, 3 landslides, 74 water erosion, 33 collapses, 7 snow damage, 25 permafrost along the high way, which frequently block the traffic and cut the highway line.Based on the field investigations, the hazard type, distribution, disaster, and the formation background are preliminarily discussed.At last, suggestions for the next step are put forward.
