| 摘 要： | 由于地形地貌、岩体土类型、人类工程活动等地质灾害影响因子不同,汉台区地质灾害分布极不均匀,表现在北部山区崩塌地质灾害密度大,中南部粘性土滑坡较多。本文在地质灾害详细调查的基础上,利用地质灾害影响因子综合指数法,进行地质灾害易发程度分区评价,并以易发区和地质灾害隐患点险情等级进行点对区的空间叠加,形成地质灾害危险程度分区评价,为汉台区地质灾害防治管理部门提供了防治对策依据,尤其对陕南移民搬迁选址提供了技术支撑。

| Abstract: | The distribution of geological hazard in Hantai district is uneven,because of differentiation among impact factors such as landform,rock and soil mass types,human project activities. Collapse mainly scatter in the northern mountains and clay landslides mainly distribute in the central and southern area. Based on the detailed survey,the paper evaluates the susceptible degree of the geological hazard with the comprehensive index method of geological hazard factors. Comparison has been made between hazard-prone areas and hazard-stricken areas so that more scientific evaluation on degrees of risk can be taken to the hazardous areas. This paper provides the theoretical basis for its prevention and cure in Haitai geological hazard department and makes contributions in technical support for emigrants in Southern Shaanxi. |
