摘要
汉台区地处秦巴山区,地质条件复杂,地形地貌差异明显,地质灾害分布极不均匀。2008年"5.12"汶川大地震和2010年陕南山洪后地质灾害频发,一定程度上制约着当地社会经济的发展。基于对汉台区地质灾害的详查,分析汉台区地质环境条件,讨论该区地质灾害的发育特征、分布规律和形成条件。提出汉台区地质灾害防治对策主要为避让措施、工程治理措施和树立警示牌。
Hantai is located in the Qinba mountain area with complex geological conditions, significantly different topographies and a highly uneven distribution of geological disasters. Social and economic development of this area is restricted to a certain extent by “5.12” Wenchuan earthquake in 2008 and geological disasters frequently occurring after the flash floods in southern Shaanxi in 2010. Based on a detailed survey of the geological hazards in Hantai, this study analyzes the geological environment and discusses the development characteristics, distribution and formation conditions of the disasters, proposing that prevention and control measures mainly include avoidance, engineering control and putting up warning signs.
