探地雷达在探测基岩顶深度中的应用
The application of GPR in detecting the depth of bedrock
摘要
Abstract
In order to cooperate with the East Tianshan-Beishanarea geochemical exploration work,we carry out the Quaternary thick-ness and bedrock surface depth detection in the Yuhai area. In order to find the bedrock surface in Yuhai area,the bedrock survey was carried out on the experimental area and the demonstration area to obtain the depth of bedrock depth, to provide depth reference data for drilling sampling,and the combined application of ground penetrating radar and single point electric sounding method in bedrock Survey. Yuhai area is located in the north of the Kanggoul fault,the results show that in the south area that the along north side of the Kangguer fracture,Neogene thinner,the depth of the bedrock can be effectively detected by the ground penetrating radar and the single-electron sounding method,There is a negative correlation between the bedrock depth and the topographic contour in the north and south direction,with a depth of 1~21 m; the bedrock fluctuation is larger in the east-west direction, showing a deeper depth in the west, more than 12 meters,the middle of the shallow,in the 4~20 m,the eastern part of the 8~30 m,white board to the central part of the region can be greater than 20 meters,but the range is small. The engineering practice shows that it is feasible to combine the ground penetrating radar and single-point electric sounding method in Yuhai bedrock survey to provide reliable basic data for later drilling.关键词
