摘要
１９９５年６～７月，成昆铁路蒲坝小龙滩沟５次暴发泥石流。因山前区古泥石流堆体“复活”补给了大量物质，酿成了成昆铁路近年较大的一处泥石流灾害。本文从降雨、河槽侵蚀机理等方面进行了成因探讨，并提出了以疏导工程防止泥石流改道、控制古堆体活动为主的整治对策。
In June and July, 1995, debris flow broke out for five times in Xiaolongtan Gully of Puba Basin. Because a large amount of materials were given by relapsing old debris flow sedimentin in fore mountain region, Chengdu Kunming Railway suffered a serious debris flow damage. The formation has been studied from railfall, river erosion mechanism and others in this paper. In order to prevent debris flow′s detour and control the activity of old sediment, the dredge project is presented as a major countermeasures.
