Application Research of Rock Image AI Recognition Technology in Geotechnical Engineering Investigation in Sichuan-Chongqing Area

There are a large number of red bed soft rocks distributing in Sichuan-Chongqing region. In the traditional geotechnical engineering investigation, the identification of rock lithology and weathering degree are characterized by strong subjectivity, low efficiency and high cost. In order to improve the efficiency of geotechnical engineering investigation of similar strata, improve the traditional investigation work mode, and improve the economic and social benefits of enterprises, AI recognition system for red bed soft rock image is proposed, AI recognition system has been successfully applied to many projects such as plot C06 of Chongqing Wanda cultural tourism city. Through field verification, the accuracy of rock weathering degree and lithologic image recognition are over 90%. The intelligent identification system has developed several versions such as wechat applet, app and web system, which can be directly used in the field geological survey of similar situation to assist geological workers in the investigation work to achieve the intelligent identification and classification of red bed soft rocks.
