绵竹清平乡玉麦棚子沟泥石流在"5·12"地震后频繁爆发大规模泥石流,因此有必要对其危险性进行评估。着眼于泥石流形成的基本条件,进行了。感、现场工程地质调查,分析了泥石流水动力条件、物缘转化关系、活动性等,并通过地灾危险性评估得到:玉麦棚子沟泥石流属暴雨沟谷型泥石流。目前该泥石流沟所处阶段为发展期,近期内再暴发中~小型泥石流的可能性大。
綿竹清平鄉玉麥棚子溝泥石流在"5·12"地震後頻繁爆髮大規模泥石流,因此有必要對其危險性進行評估。著眼于泥石流形成的基本條件,進行瞭。感、現場工程地質調查,分析瞭泥石流水動力條件、物緣轉化關繫、活動性等,併通過地災危險性評估得到:玉麥棚子溝泥石流屬暴雨溝穀型泥石流。目前該泥石流溝所處階段為髮展期,近期內再暴髮中~小型泥石流的可能性大。

Giant deribs flow hazard occurrs frequently in Yu-maipengzi Gully in Qingping, after "5.12" earthquake. Focused on the basic formation, it was on the research of hydrodynamic conditions, transforming relationship and activities by field investigation and map-ping. It concluded through risk assessment that deribs flows were trig-gered by heavy rainfall in the gully. Yumaipengzi debris flow is in de-veloping stage and the outbreaks of medium or small scale debris is probable in the near future.
