岩溶和非岩溶地区1∶5万地质灾害调查野外工作侧重点分析——以广西贺州市平桂区为例
|
摘要
随着全国1∶5万地质灾害调查的开展,及新规范的出版,调查工作更加标准化。平桂区是2018年广西壮族自治区1∶5万地质灾害详细调查工作下达任务的县(市、区)之一。平桂区地质环境条件复杂,其南部为碎屑岩地区,中部多为岩溶地区,北部姑婆山一带为花岗岩地区,且人类工程活动频繁,为本次研究工作提供了样本。岩溶地区不仅要以崩塌、滑坡、泥石流调查为主,还需要对岩溶塌陷和危岩这两种地质灾害进行足够的重视,研究成果可为其它岩溶地区地质灾害调查提供借鉴与指导。
With the development of 1∶50,000 geological disaster investigation nationwide and the publication of new standards, the investigation work is more standardized.Pinggui district is one of the counties(cities and districts) tasked with the detailed investigation of 1∶50 000 geological disasters in guangxi zhuang autonomous region in 2018.The geological environment of pinggui area is complex, with the detrital rock area in the south, karst area in the middle and granite area in the north of the great aunt mountain area, and the human engineering activities are frequent, which provide samples for this study.In karst areas, not only the investigation of collapse, landslide and debris flow, but also the two types of geological hazards, such as collapse and dangerous rock, should be paid enough attention to. The research results can provide reference and guidance for the investigation of geological disasters in other Karst areas.
