基于红外热像技术的上海基岩残丘地质灾害隐患调查

Investigation of potential geological hazards in the bedrock monadnock area of Shanghai using infrared thermal imaging technology

松江是上海唯一有基岩出露的地区,山体小范围岩石崩塌时有发生,而松江区近几年又大力发展旅游文化产业,岩石崩塌等对人身财产与生态环境造成了不利影响。本文在对上海松江地区基岩残丘地质灾害隐患调查中,探索采用红外热像技术,对岩石脱空、裂隙发育、表面风化、岩壁渗水等隐患点的红外数据特性进行分析,取得良好效果。

Songjiang district is the only area in Shanghai with bedrock outcropping.A small range of rock collapse occurred in the vicinity of the mountain.In addition,Songjiang district has developed the tourism industry in recent years,which has led to adverse effects on people's personal property and the ecological environment.In this study,infrared thermal image technology was used in the investigation of hidden geological hazards of the rock debris in the Songjiang area of Shanghai and good results were obtained.Further,the infrared data characteristics of hidden spots such as rock voids,cracks,surface weathering,and rock wall seepage are briefly described.
