粤港澳湾区 1∶ 50 000 斗门镇幅工程地质调查及岩土样品试验数据集

This dataset was created as a result of the "Environmental Geological Survey (1:50 000) in the Guangdong-Hong Kong-Macao Greater Bay Area" project of the China Geological Survey in 2017. Based on previously collected geological information, we have carried out a 1:50 000 engineering geological survey in Doumen on the west bank of the Pearl River Estuary in the Guangdong-Hong Kong-Macao Greater Bay Area and compiled the 1:50 000 engineering geological map and specifications. This dataset was established based on the survey and analytical data of the samples. The dataset has 10 types of data in two categories:survey data and experimental test data, including 168 series of basic survey data, 53 series of data from field verification and remote sensing interpretation, 22 series of data from the integrated geological field survey, 77 series of data from the engineering geological survey, 23 series of data from the geological hazard survey, 13 series of data on the basic information of boreholes, 583 series of data from in-situ test results, 36 series of data from rock sample tests, 130 series of data from geotechnical tests and 669 series of data from field pictures, in total 1 774 series of data. This dataset will help us understand the engineering geological conditions of the west bank of the Pearl River Estuary in the Guangdong-Hong Kong-Macao Greater Bay Area and evaluate geological hazards such as soft ground subsidence, collapse, landslide and unstable slopes.
