摘要
为分析锚杆支护的效果,建立了圆形巷道锚杆支护分析的力学模型,考虑了锚杆支护预紧力的作用。利用该模型分析表明,提高锚杆支护预紧力,对减小围岩的强度损失,提高锚杆支护的效果,有着重要的作用。
In order to analyze the effect of bolting support, an analytically mechanical model on the basis of bolting support in circular drift is built, the process of which has taken into account the operation of pretightening force of bolting support. After analyzing through the model, it indicates that enhancing pretightening force of bolting support plays an important role in reducing the strength of surrounding rock and raising the effect of bolting support as well.
