摘要
对于采用锚杆支护的巷道，根据流变力学的基本理论，分析了在两向等压条件下锚杆支护区围岩应力———位移随时间的变化规律，建立了与时间有关的锚杆支护破坏准则，对地下巷道的支护设计具有一定的参考价值。
For bolting roadways,according to the basic theory of rheologic mechanics,this paper analyses the changing law of stress-dispacement in bolted surrounding rock with the lapse of time under the two-way isobaric condition and builds the bolting fracture criterion related to the time.The results have a certain reference value for the support design of underground roadways.
