摘要
本文从拉拔时锚杆受力分析入手，结合锚杆实测应力分布曲线，给出了基于岩性和锚固方式的锚杆支护强度的估算法。
According to the analysis on the stress status of bolt during pull - out test accompanied with the field measured curves of stress distribution of the bolt , the calculation method of anchoring strength of bolting is given based on rock properties and anchoring style.
