摘要
///In the anchor support construction with large-tonnage and super-long hole depth, the borehole deviation control greatly influences the effect of pre-stressed cable anchorage. Based on the analysis on the causes of borehole inclination, the paper put forward the prevention and control measures for large depth anchorage cable hole.
