摘要
本文将文献〔4〕所得围岩作用于全长粘结型锚杆的剪力均分于锚杆微段的围岩体积内,并假设原岩应力处于二向等压条件下,推导出圆形井巷在全长粘结型锚杆支护后围岩中应力和位移的表达式,然后对所得结果进行了分析讨论。
Formulas for calculating stress and displacement of wallrocks under the full-column cemented rock boliting and axisymmetric conditions are given in this paper, and the worked out results are analysed and discussed as well.
