| Abstract: | In this Paper the authors studied the geological hazard's type ,feature and distribution law associated with a planned road in northeast of Yunnan, analyzed their influenced factors and mechanisms. The development of geological hazards were influenced by strata's lithology, rock-texture, geological structure, earthquake, hydrology, climate, human engineering activity and so on. In the study area geological hazards mostly are rockfall,landslide, mud-rock flow, karst and ground collapse, in addition, soft clay, expensive soil and sand liquefaction distribute in the area. The different geological hazards destroy and influence the road in the different mechanism. |
