探地雷达在丘陵山区滑坡地质灾害隐患勘查中的应用
Application of ground penetrating radar to geological hazard exploration of landslides in hilly and mountainous areas
摘要
Abstract
The geological environment in the hilly and mountainous areas of northern Guangdong is fragile,and landslide geological disasters occur frequently.It is of great significance to use cost-effective exploration methods to explore landslide hazards,determine their spatial form and predict their development trends.In this paper,GPR is used to explore a landslide hazard in Longchuan County,Heyuan City,Guangdong Province.The exploration results show that the reflections of GPR waves on the sliding surface of landslide and the weathering interface of bedrock are obviously different.The geological profiles are clearly layered,which accurately and reliably depict the geological bodies such as overburden,weathered layer and bedrock.The detection results are basically consistent with the drilling data.关键词
