龙门山银厂沟地震次生灾害分布规律研究
|
摘要
"5.12"汶川地震造成的次生地质灾害十分严重。在分析遥感解译资料的基础上,结合现场复核调查,对龙门山地区的银厂沟白水河沿线地震次生灾害分布特征,及其与高程、距断层距离、坡度、岩性等地形地质要素的关系进行了研究,为灾区建设以及同类高烈度区的工程建设提供了重要的基础地质信息。
The "5.12" Wenchuan earthquake caused severely secondary geohazards.Based on the analysis of remote sensing data and field survey,the distribution of earthquake-induced geohazards along the Baishui River in Yinchanggou of Longmenshan area was studied,and its relationships with the topographic and geological factors,such as elevation,distance from fault,slope gradient,and lithology,were investigated.The research can provide the key geological guidance for the reconstruction and project construction in the area with similarly high earthquake intensity.
