【摘要】 以滇藏铁路林芝-拉萨段为例,利用Google Earth对两拟选线路方案沿线的活动断裂,滑坡、泥石流、崩塌等地质灾害进行遥感解译,并制作三维飞行动画。研究发现北线方案主要受泥石流影响,南线方案活动断裂、滑坡、崩塌、泥石流均较发育,从工程地质条件来看北线优于南线。更多还原

【Abstract】 With Linzhi-Lasha section of Yunnan-Tibet railway taken as an example,the Google Earth images are used for the interpretation and 3D virtual flying of geo-hazards along the selected railway such as landslide,debris flow,collapse and wind-sand.It was found that the north line plan is mainly affected by the debris flow,while the south line plan is mainly affected by the active fault,landslide,collapse and debris flow,and the geological condition of north line is better than that of south one.更多还原
