摘　　要：通过对宝成铁路凤县段地质灾害的详细调查,分析发现宝成铁路沿线地质灾害的主要发育类型为滑坡、崩塌和泥石流灾害,发育规模主要以小型为主。在调查分析基础上研究了这三类地质灾害的发育特征,并对其分布规律进行剖析,结果表明宝成铁路凤县段地质灾害具有明显的空间性与时间性。空间上主要集中于两个区域:断裂影响区和土质影响区;时间上则主要集中在雨季。该研究对宝成铁路凤县段地质灾害的防治具有重要意义。Based on the detailed investigation of geological disasters along Baoji - Chengdu railway in Fengxian district, the types of geological disasters are summarized. There are there major disasters： landslides, collapse, and debris flow. The disasters are mainly small scale. On this basis, the devel- oping characters of disasters and distributing rules are studied. The results show that the geological disasters in Fengxian district have significant spatiality and timeliness. The geological disasters in space mainly focus on two areas： the zone affected by fracture and soil. The geological disasters occur mainly in the rainy season. The study is useful to prevent and control the geological disasters in Fengxian district.
