AI Technical Summary
When conducting vertical series of cave exploration in karst landform areas, the existing core drilling method is costly and has a limited detection range, while the results of tube wave detection are easily affected by the differences in the size of the caves, resulting in poor stratification accuracy and difficulty in accurately predicting the strata.
A method combining engineering zoning, borehole data processing, and pipe wave detection and data processing was adopted. A geological model was established by combining borehole data and pipe wave detection results. Rock and soil strata were classified by weighted K-means clustering algorithm. The coding of borehole data and the wave velocity difference characteristics of pipe wave detection data were combined with computer programming analysis to establish an accurate geological model.
It improved the accuracy of stratification of vertically connected caves in karst landforms, reduced errors, increased exploration efficiency, and achieved higher stratification accuracy and lower errors.
