摘要
麻柳沟位于都江堰市龙池镇龙溪河右岸,"5.12"地震后麻柳沟流域内产生了大量的崩滑体,物源丰富。2010年8月13日,在强降雨作用下该沟暴发中等规模的泥石流,沟口堆积体积达8×104 m3,损毁了沟口处3户居民的房屋,并於埋了龙池景区公路。本文通过麻柳沟的实地调查取样和洪痕断面测定,分析了麻柳沟泥石流的形成条件和基本特点,并通过计算泥石流的容重、流速、流量等静动力学特征参数,对该泥石流沟的发展趋势进行预测。
Maliu gully debris flow located in the right bank of Longxi river in Longchi town,Dujiangyan city.After ＂5.12＂earthquake,basin of Maliu gully generated a lot of sliding masses and provide rich material resources.August 13,2010,Maliu gully has outbreak medium-sized debris flow under the action of heavy rainfall.Mizoguchi deposits amounted to 8 × 104m3,Damaged three resident’s houses and was buried Longchi scenic highway.Analysis of the formation conditions and basic characteristics of debris flow Maliu gully based on the field investigation at Sampling and measurement of flood marks Cross Section.By Calculated the density of debris flow,flow rate,Static and kinetic parameters,forecasting the development trend of the debris flow,and put forward appropriate prevention recommendations according to its hazard.
