摘要

摘要: 为研究扩大头滑移式锚杆的恒阻力值与锚杆尺寸之间的关系,在恒阻大变形锚杆的恒阻力值弹性理论基础上推导出弹-塑性理论公式,使其适用于扩大头滑移式锚杆的恒阻力值预测。利用数值模拟软件对5种工况下的锚杆恒阻力值进行研究,并基于室内试验对三种工况数值模拟结果的验证表明:数值模拟模型与试验结果相差较小,模型比较合理;弹-塑性理论公式计算出的阻力理论值与数值模拟得到的阻力值有较好的吻合度。

Abstract: In order to study the relations among the constant resistance value of sliding anchor bolts with expanded heads and the anchor bolt sizes, the elastoplastic theoretical formula was deduced based on the elastic theory for the constant resistance of large deformation bolts, which could be suitable to predict the constant resistance values of sliding auchor bolts with expanded heads. The numerical simulation software was researched the constant resistance values in five working conditions, and the simulation results of the three working conditions were contrasted with the results from indoor experiments, and the results showed that the numerical simulation model had less differences from the experimental results, and the model was more reasonable; the theoretical resistance values calculated by the elastoplastic theoretical formula were in good agreement with the ones by numerical simulations.
