分类结果表明，高地应力条件下，Q系统的适用性较好，RMR分类、HC分类、BQ分类适用性均差。

The classification results show that the Q-system has a good applicability and the other three methods have a bad applicability in the conditions of high field stress .

BQ分类对岩石强度过于敏感。其分类结果在高地应力区过于保守。

The BQ method is too sensitive to the rock strength , it 's classification results are often conservative in the high field stress areas .
