摘　　要：阳(平关)安(康)铁路位于陕西省南部,沿线地质条件复杂,灾害种类多且规模大,对行车安全的威胁与日俱增。为了解地质灾害对铁路运营安全的影响,同时也为后续的安全风险评价以及整治防范提供现场资料,在大量野外实地调查与资料整理的基础上,详细介绍和分析阳安铁路地质灾害的类型、分布以及成因,并借鉴既有线路灾害的整治经验,提出相应的防治措施。结果表明:崩塌、溜坍是阳安线主要的地质灾害类型,同时滑坡与泥石流也是不可忽视的地质灾害;由于铁路沿线多位于山区,复杂地质条件以及大气降水是诱发地质灾害的主要因素。Yangpingguan-Ankang Railway is located in the south of Shaanxi province along with complex geological conditions and many kinds of geological disasters threatening increasingly the railway operation.In order to understand the impact of the geological disasters on railway operation and provide field data for subsequent risk assessment and remediation,this paper analyzes the types,the distribution and the causes of the geological disasters based on a large number of field investigations and data collations,and proposes corresponding countermeasures with reference to the experiences in existing geological disasters remediation. The results show that collapse and topsoil slip are the main disasters,and landslides and debris flow should not be neglected; the complex geological conditions and rainfall are the main factors to trigger geologic disasters.
