陕西宝鸡地区黄土工程边坡分类及防治现状

Classification of loess engineering slopes and present situation of prevention and control in Baoji area,Shaanxi

根据地质灾害详细调查、工程地质测绘及综合分析等方法,对宝鸡地区黄土工程边坡的特征、发育的灾害类型及工程防治存在的主要问题进行了重点研究,结果表明:按扰动类型可将本区工程边坡划分为建筑工程边坡、线性工程边坡、水利工程边坡和采矿工程边坡4大类;工程措施选择不恰当、一些高危边坡防治不彻底及部分危险性较小边坡的过度防治是目前边坡防治存在的主要问题;加强对黄土工程特性的研究、研发适宜于宝鸡地区黄土灾害发育特征的防治关键技术及做好分期防治规划是提升本区灾害防治水平的关键,研究成果旨在为宝鸡黄土工程边坡地质灾害防治提供支撑。

By means of detailed field investigation of geological disasters,engineering geological mapping and comprehensive analysis,the authors studied the characteristics of loess slope engineering,the disaster types,present situation of prevention and control,and the main problems of engineering protection in the areas of Baoji.The results show that the loess engineering slopes,according to engineering disturbing types,can be divided into four categories: construction slope,linear engineering slop,water conservancy project slope and mining engineering slope.It is identified that the main problems of prevention and control of slopes are inappropriate slope control measures,incomplete slope control measures for highly dangerous slopes and excessive control of low-risk slopes.Therefore the key to improve the level of disaster prevention in this area is to strengthen the research on loess engineering characteristics,develop the key prevention technologies suitable for the loess disaster in Baoji area and make a prevention and control plan by stages.The research results are expected to provide technical support for the prevention and control of loess engineering slopes.
