中文摘要	溜石坡是中巴公路北部地区发育的一类特殊高寒高山冰川地带的边坡地质灾害类型,时常造成中巴公路淤积与交通中断。溜石坡在形态、沉积结构与生成环境等方面与分布在中国川藏公路沿线典型的溜砂坡存在显著不同,由此二者在颗粒组成与粒度分布等方面表现出典型差异。通过实地考察、样本测试及理论分析,研究表明其溜石坡具有分布在干旱、半干旱高寒高山冰川地带,发育在泥岩、板岩及石灰岩分布区及崩积层存在二元结构等典型特征;分析了溜石坡形成需要的4个阶段:物源区岩块脱落、风化残积、淋溶固结及蠕动前移,初步提出了深部固砂、重力式挡石墙、明硐(或棚硐)及落石台等溜石坡防治对策,这些方法将为对其进一步公路灾害防治研究提供参考。
英文摘要	Gravel-sliding slope is a typical geo-hazard type pervasively developed over the alpine glacier region along International Karakoram Highway,which has caused massively casualties and property loss from continuous geo-hazard attacks since KKH was put into operation in 1981.Some basic formation conditions between gravel-sliding and sand-sliding along the Sichuan-Tibet Highway are significantly different, such as morphology,sedimentary texture,and environmental causes etc.,and the typical differences are mainly showed at grain composition and size distribution.Based on field investigation,sample test, and theoretical analysis on the gravel-sliding slopes along international Karakoram Highway(KKH)from 2008to 2011,this paper explores some typical characteristics that are distributed in the arid and semiarid alpine glacier region,developed in the mudstone,slate and limestone areas,and possessed dualistic structure coluvium.The paper also analyzes the four formative stages:formatting gravel-sliding,weathered eluvial, eluviation consolidation,and forward creep.This paper also discusses the preventive measures, such as deep sand consolidation,gravity retaining wall,shed tunnel etc.The achievements of this research not only present important academic significance and engineering value,but also provide a theoretical guiding role for further study of gravel-sliding slope.
