扩大锚注支护应用范围的数值研究

Numerical studying on bolting and grouting to enlarge its scope of application

通过对四个巷道支护模型的数值模拟，研究了锚注支护的时间效应，为将锚注支护推广到掘进巷道中提供了理论依据。

Based on the numerical simulation of four support models, the authors have studied the time effect of bolting and grouting, provided the theoretical basis for enlarging the scope of application of bolting and grouting to drift excavation,and pointed out the problems which is worth paying attention to.
