京山县三阳镇岔河滑坡基本特征及成因分析
|
摘要
以湖北省荆门市京山县三阳镇岔河滑坡治理工程设计为基础,从地质条件入手,总结分析该区地质灾害的发育特征及影响因素等,确定该区域的滑坡基本特征主要为中型岩质滑坡,属于推移式。结合滑坡区域地质特征可知,该滑坡成因主要包括内在因素——地形地貌和物质结构,以及外部因素——水的作用和人类建房、耕种、修路等人类工程活动。同时,对滑坡成因机制进行了分析论述。
This paper based on the design of Chahe residential landslide control project in Sanyang Town of Jingshan County,Jingmen city,Hubei Province,starting with geological conditions,the development characteristics and influencing factors of geological disasters in this area are summarized and analyzed. The basic characteristics of landslide in this area are mainly medium rock landslides,which belong to the push type. According to the geological conditions,the paper summarized and analyzed the development characteristics and influencing factors of geological disasters in this area,and determined that the basic characteristics of the landslide in this area are mainly medium-sized rocky landslide,which belongs to the push type. The features of the regional geological shows that the causes of the landslide are mainly internal factors including topography and physical structure,as well as external factors including the effect of water and human engineering activities such as human building,farming and road building. Also,the mechanism for slope deformation is analyzed and discussed.
