丰沙铁路山区段坡面型泥石流特征分析及防治建议

Analysis of characteristics and prevention suggestions of slope type debris flow in the mountainous section of Fengsha Railway

既有山区铁路泥石流灾害时有发生,随着极端气候变化灾害愈发严重,极大危及铁路行车安全,尤其以坡面型泥石流的高速度、大冲击力、突发性、短暂性等特征对铁路的影响较大,严重威胁行车安全。针对山区铁路发生坡面型泥石流的水害处所,通过现场踏勘并采用遥感影像及无人机倾斜摄影技术,对水害点展开调查研究,分析坡面型泥石流特征及发生机理,并提出针对性防治措施。研究结果可为类似水害治理提供参考。

Mudslide disasters on existing mountainous railways occur from time to time,and with the increasing severity of extreme climate change disasters,it greatly endangers railway safety,especially the high speed,large impact force,suddenness,and transience of slope type mudslides,which have a significant impact on railways and seriously threaten train safety.In response to the water damage caused by slope type debris flows on railways in mountainous areas,on-site surveys were conducted using remote sensing images and unmanned aerial vehicle oblique photography technology to investigate and study the water damage points.The characteristics and mechanisms of slope type debris flows were analyzed,and targeted prevention and control measures were proposed.The research results can provide reference for similar water hazard management.
