| 中文摘要: |
| 德保县是广西地区地质灾害最为严重的县(市)之一，地质灾害类型主要有滑坡、危岩、崩塌、泥石流、地面塌陷、不稳定斜坡等。为了查明德保县地质灾害发育的地质环境条件和地质灾害类型，分析灾害的形成条件及影响因素，在德保县1∶5万地质灾害详细调查的基础上，通过实地踏勘，共核查了全县现有各类地质灾害396处。分析研究表明，该区地质灾害的形成条件主要与该区的地形地貌、岩土体类型、地质构造、降雨、地下水、人类活动等息息相关，而降雨和人类工程活动等因素则是形成地质灾害的重要影响因素。开展广西德保地区各类地质灾害的形成条件与影响因素研究，对该地区的地质灾害监测预警和防治工作具有重要意义。 |
| 英文摘要: |
| Debao County is one of the most serious geological disasters in Guangxi. The main types of geological disasters are landslide, dangerous rock, collapse, debris .ow, ground collapse, unstable slope and so on. In order to .nd out the geological environment conditions and types of geological hazards in the development of geological hazards in Debao County, and to analyze the formation conditions and in.uencing factors of geological hazards, based on the detailed investigation of 1∶50,000 geological hazards in Debao County, China, a total of 396 geological disasters have been veri.ed. The analysis shows that the formation conditions of geological hazards in this area are closely related to the topography, geomorphology, types of rock and soil mass, geological structure, rainfall, groundwater, human activities, etc. , the rainfall and human engineering activities are the important factors of the formation of geological disasters. The study on the formation conditions and in.uencing factors of various geological disasters in Debao area of Guangxi is of great signi.cance to the monitoring, early warning and prevention of geological disasters in this area. |
