摘要

红岩泥石流沟位于四川省什邡市蓥华镇,该地区受"5.12"大地震影响,沟内斜坡发生大规模山体崩塌。崩塌堆积体集中于红岩沟内,形成了泥石流的物源。若遇上强降雨,红岩沟有可能发生泥石流地质灾害。通过调查研究表明,红岩泥石流潜在汇水区域呈扇形分布,物源区汇水面积约1.749km2,物源丰富。采用地质灾害危险性分析方法,分析研究区泥石流危险性指数,红岩泥石流属于中等易发泥石流。对红岩泥石流的研究,有助于分析泥石流的现状危险性程度及其发展趋势。对其采取必要的防治措施,确保该区域村民生命财产安全。
Hongyan debris flow is located in Yinhua town,Shifang city,Sichuan province.Affected by the "Wenchuan 5.12 Earthquich",large-scale mountain slope trench collapse happened in this area.Accumulation of collapsed body focused in Hongyan valley,forming a debris flow material source.In heavy rainfall,geological disasters of debris flow may occur in Hongyan valley.The research result shows that the potential catchments area of debris is in fan-shaped,and catechments area is about 1.749 km2 with rich source of materials.In this paper,we uses geological hazard risk analysis method to analyze that risk index of debris flow in the study area is belong to moderately easy to happen debris.The research to the Hongyan debris is help to analyze the current situation,risk levels,and trend of debris.To take the necessary measures to prevent and control the debris can ensure the safety of lives and property of the villagers in this region.
