Abstract :
Yichang-Wanzhou railway with total length of 377 km was constructed in the mountain region presenting the most complex karst geological conditions in the world. Several collapses happened in its artificially trenched sections since this railway opened in the December of 2010. We proposed GPR technique for accurate location of karst cavities and tubes beneath the railway basement for grouting reinforcement.
