Since the buried cultural relics are threedimensional (3-D) objects in nature, 3-D survey is more preferable in archeological exploration. 3-D Ground Penetrating Radar (GPR) survey based on very dense data in principle, however, might need much higher cost and longer time of exploration than other geophysical methods. We developed a small-scale continuous(More)
The highway of Yongweol-ri, Muan-gun, south-western part of the South Korean Peninsula, is underlain by the abandoned of subsurface cavities, which were discovered in 2005. These cavities lie at shallow depths with the range of 5∼15 meters below the ground surface. Numerous subsidence events have repeatedly occurred in the past few years, damaging(More)
The existence probability (Ep) of lime silicate cavities, which affect ground stability, was analyzed using borehole, electrical resistivity, and gravity data. A neural network training function was used to estimate the contribution coefficients of physical properties that play a part in determining the Ep. For this process, the resistivity and density(More)
