摘要
滑坡隐患位于低山区与河谷阶地交汇处,主要由松散岩性组成,滑体斜长约125m,宽约100m,发生整体滑动的可能性较大。滑坡威胁对象主要是坡体下方住户共计17户71人53间房屋、1个村卫生室,威胁财产1000万元,危险性大。通过构建滑坡颗粒流数值模型,判断该滑体运动总持续约100s,主滑时间约50s,滑坡发生时,坡下居民基本没有反应时间,该滑坡需进行及时治理。滑坡治理,主要采取抗滑桩+挡墙+截、排水+监测的综合防治措施,可产生较好的生态、环境、社会效益。
The hidden danger of landslide is located at the intersection of low mountain area and valley terrace,which is mainly composed of loose lithology.The landslide body is about 125m long and 100m wide,and the possibility of overall sliding is large.The landslide is mainly threatened by 17 households,71 people,53 houses and 1 village health room,threatening property of 10 million yuan and posing great danger.Through the construction of landslide particle flow numerical model,it can be judged that the total movement duration of the landslide body is about 100s,and the main sliding time is about 50s.When the landslide happens,the residents under the slope basically have no reaction time,and the landslide needs to be treated in time.The comprehensive control measures of landslide control,including anti-slide pile+retaining wall+intercept,drainage+monitoring,can produce better ecological,environmental and social benefits.
