滑坡灾害特征及其治理技术研究——以驻马店市乐山林场为例

Research on characteristics of landslide disaster and its control technology:taking LeshanForest Farm in Zhumadian City as an example

为了消除河南省确山县三里河确山县公安局森林公安分局办公楼后滑坡灾害,研究了其灾害特征,研究区属活动性滑坡,坡面呈阶梯状,拉张、剪切裂缝分布多达17条,长2~29 m,水平位移0.05~1.00 m,垂向位移0.05~2.50 m,滑坡现状稳定性差,危害程度中型,危险性大。分析了滑坡治理技术,主要包括边坡削方减载技术、挡土墙和浆砌石护坡技术、植树造林技术、警示牌和标示技术等。研究可为开展滑坡灾害防治施工提供技术依据。

In order to eliminate the landslide disaster behind the office building of Queshan County Public Security Bureau Forest Public Security Bureau,Sanlihe,Queshan County,Henan Province,this paper studies its disaster characteristics.The study area is an active landslide,the slope is stepped,17 tension and shear cracks distributed,with a length of 2~29 m,a horizontal displacement of 0.05~1.00 m,and a vertical displacement of 0.05~2.50 m.The current stability of the landslide is poor,the damage degree is medium,and the danger is high.The treatment technology is analyzed,including slope reduction and load reduction technology,retaining wall and masonry slope protection technology,the afforestation technology,the warning sign and the marking technology.The research provides a technical basis for carrying out the prevention and control technology construction.
