摘      要：The lag in quantitative methods and detection techniques for geologic information has resulted in time-consuming and human-experienced geologic analysis in *** indicators of rocks can be used to identify adverse geology and to explain the intrinsic causes of damage to normal *** study proposes a method to identify adverse geology by extracting and imaging the indicator *** mapping relationship between rock components and geologic bodies is quickly determined by indicator element extraction based on factor analysis,and then the data are gridded for image *** location and size of the target adverse geology are visually identified through the distribution images of the indicator elements,thus reducing data dimensions and analysis time.A non-destructive,in-situ and fast element detection technique in tunnels was adopted to speed up the process of geology *** accuracy of the detection was validated by comparing field and laboratory test *** study further confirms and refines the previous research,and the results provide references for geological,mining and underground projects.
