摘　　要：文中摒弃过去片面地通过增大预紧力和提高锚杆质量来提高支护效果的研究方法,从锚杆与围岩构成的"支架—围岩"体系入手,根据围岩不同变形阶段与锚固力的关系,结合围岩强度和位移的时间效应,提出锚杆初锚力要"恰当",工作锚固力要有"余量"的理论。According to the relationship between different surrounding rock deformation stage and anchor force,combined the time effect of rock strength and displacement,the paper pointed out that the setting force of anchor bolts should be appropriate and effective force of anchor bolts should have some abundant.

关 键 词：锚固力 时间效应 初锚力 工作锚固力
