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)
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)
