标题：EXPLORATION OF THREE-DIMENSIONAL DISTRIBUTION CHARACTERISTICS OF SHALLOW SLIDING SURFACES: A CASE STUDY OF THE CHA'AN LANDSLIDE IN DALIAN CITY, LIAONING PROVINCE, CHINA
摘要：It is the aim of landslide investigation to quickly and accurately explore the three-dimensional distribution characteristics of shallow-landslide surfaces. The shallow transient electromagnetic method, combined with the rock-mass P-wave velocity-logging method and borehole lithology data can obtain ideal results through comprehensive exploration. In order to verify the TEM data and use the existing boreholes, the P-wave velocity in field (VPF), the P-wave velocity in the laboratory (VPL), and the saturation compressive strength of rock mass were measured, and the basic quality value (BQ) was calculated. Finally, the basic quality classification and integrity of rock mass were examined. In the study area, representative boreholes ZK06, ZK07, and ZK08 were compared and analyzed in resistivity and BQ. In addition, the correlation of the measured data of the two methods is analyzed, and the ideal correlation coefficient is obtained. Finally, a new comprehensive geophysical method for three-dimensional sliding surface detection is applied.
