MECHANISM ANALYSIS AND RISK ASSESSMENT OF THE DANGEROUS ROCK MASS IN THE NORTHERN SLOPE OF CHANGBAI MOUNTAIN
-
摘要: 长白山地区近期地质构造、岩浆活动强烈，地壳不断上升，是我国地质灾害频繁发生的地区之一.通过对长白山北坡登山长廊上方边坡危岩体的分析，考虑崩塌形成的影响因素、崩塌类型，总结出崩塌变形破坏机理及流沙坡形成机理；根据地形、地貌以及岩体工程地质特征，对危险区进行分区评价，为治理提供科学依据.Abstract: The Changbai Mountain area, with intense geological movement, active magmatism and continuously rising crust, is a region where geological hazards occur frequently. By analysis on the dangerous rock mass above the tourist corridor on the northern side of Changbai Mountain, considering the influencing factors and types of collapse, this paper summarizes the deformation mechanism of the collapse and the formation mechanism of quicksand slope. Based on the topography, geomorphology and engineering geology of the rock mass, the dangerous zones are divided, with assessment for the risk of geological hazards, which provides a scientific basis for the treatment of the potential geological hazards.
