摘要
通过对斯巴呷拉达沟的野外勘查,判定该沟泥石流为地震触发。估算表明,地震导致流域内发育6处崩塌体,总面积17 047m2,松散固体物质总量为11.02×104 m3。在分析泥石流形成条件与发展趋势的基础上,提出泥石流减灾方案。
Field surveys of show that debris-flows occurring in the gully were triggered by the Lushan earthquake.It resulted in 6landslides with a total area of 17 047m^2 and total loose solids of 11.02×10^4 m^3.Based on an analysis of the occurrence conditions and the development tendency of debris-flow activity,the article proposes mitigation measures.
