Abstract:

Unfavorable geological conditions were encountered in anchor cable construction for Changsha Ice and Snow World, it was difficult for drilling and hole completion. In view of the construction difficulties under poor geological conditions, the poor geological conditions evaluation basis were put forward, the treatment of pipe-sticking, hole collapse, water seepage, karst and fault were carried out in the drilling process with good effects.
