摘要
本文以托板与围岩相互作用为前提,导出了托板反力表达式,并着重分析了托板对全长锚固锚杆杆体内力的影响,得出了对全长锚固锚杆机理的若干新结论。
Based on the action of bearing plate and surrounding rock,the formula of reacting force of bearing plate is derived. The influences of bearing plate on the internal force of overall reinforced bolts are analysed and some new conclusions of overall reinforced bolts mechanism are acquired.
