摘　　要：翠峰镇位于西安市周至县西南部,为典型的黄土丘陵地区,地形地貌复杂多样,沟壑纵横,地质环境条件差,在雨季降雨的侵蚀作用和人类工程活动的影响下地质灾害发生频繁,特别是以黄土梁、峁组合而成的黄土丘陵区,地质灾害更为发育。本文以野外实地调查为基础,勘探资料及实验数据为辅,对研究区内地质灾害的发育规律进行较为系统深入地研究。通过调查孕灾地质环境条件和历史灾情,识别了新的地质灾害隐患;根据翠峰镇地质灾害发育特征和分布规律,得出6处滑坡均为土质滑坡且为浅层滑坡,1处崩塌为切坡诱发的坠落式黄土崩塌;分析了地质灾害形成条件和影响因素,主要与地形地貌、工程地质岩组、斜坡结果、水文条件以及人类工程活动有关。根据这些调查成果,及时更新了地质灾害调查数据库,完成了地质灾害风险调查数据信息化工作,为翠峰镇防灾减灾、国土空间规划和用途管制等提供基础依据和技术支撑。Cuifeng town is located in the southwest of Zhouzhi county,Xi’an city.It is a typical loess hilly area with complex and diverse terrain,crisscrossing gullies,and poor geological environmental conditions.Under the erosion effect of rainy season rainfall and the influence of human engineering activities,geological disasters occur frequently,especially in the loess hilly area composed of loess beams and hills,where geological disasters are more developed.Based on the field investigation,supplemented by exploration and experimental data,this paper conduct a systematic and in-depth study on the development laws of geological hazards in the research area.By investigating the geological environmental conditions and historical disasters,new geological hazards were identified;According to the development characteristics and distribution patterns of geological hazards in Cuifeng town,a total of 6 landslides were found to be shallow soil landslides,and one collapse was falling loess collapse induced by slope cutting;Through analysis on the formation conditions and influencing factors of geological hazards,they are mainly related to terrain and landforms,engineering geological rock formations,slope results,hydrological condition,and human engineering activities.Based on these survey results,the geological hazard survey database was updated in a timely manner,and the informatization of geological hazard risk survey data was completed,which provides a basic basis and technical support for disaster prevention and mitigation,land and space planning and use control in Cuifeng town.
