陕西泾阳县地质灾害发育特征及形成条件

泾阳县是咸阳市辖县之一,地质构造复杂,大断裂发育,岩土体结构类型较复杂,人类活动强度大,降水量大且集中,地质灾害发育。该文分析了泾阳县地质灾害的类型、规模、发育特征和分布特征,进而分析了地质灾害的形成条件。分析表明,地质灾害发育的控制因素主要有地形地貌、地质构造、地层和岩土体结构、坡体地质结构等,而地下水和植被是地质灾害的影响因素,人类工程活动、大气降雨和地震是地质灾害的促发因素。

Characteristics of geological hazard development and formation conditions of geological hazards in Jingyang County of Shaanxi Province formation analysis

Jingyang County belongs to Xianyang City. In the county, geological structure is complicated, rock and soil structure types are diverse, human activities are strong and large diversity in different areas; rainfall is big and concentrated, and geological hazards are developed. In this paper, geological hazards in types, scale, development and distribution characteristics in Jingyang County of are analyzed, as well as formation conditions. The result of analysis shows that the main controlling factors for the development of geological disasters are landform, geomorphology, geological structure, strata and rock-soil structure, geological structure of slope, and so on. Influencing factors of geological hazards are groundwater and vegetation., trigger factors are. human engineering activities, atmospheric rainfall and earthquake.
