| 摘 要： | 本文对Oden等提出的非局部摩擦模型进行了修正，得到了修正后的非局部摩擦模型，并应用于岩土工程问题。文中利用Mindlin问题的位移解导出了岩体灌浆锚杆沿杆体表面所受的剪应力的弹性解,对岩体灌浆锚杆进行非局部摩擦分析，在简化的情况下，得到了在修正后的非局部摩擦模型下的岩体灌浆锚杆侧剪应力的积分形式，再用Maple程序求解，将其所得的结果与局部摩擦(库仑摩擦)模型下的侧剪应力进行比较，结果表明是合理有效的。

| Abstract: | The nonlocal friction law proposed by Oden et al was modified and the modified nonlocal frication model to analyze the geotechincal problems was used. Based on Mindlin's solution of displacement, an elastic solution of shear stress on the bolt surface for grouting bolt in rock was derived. The grouting bolt in the rock was analyzed by using the modified nonlocal frication model, the integral form of shear stress was obtained and solved by programming Maple language, and its numerical solution was given. The nonlocal effect on the contact surface stress distribution is shown here. Compare with the solution to the local frication law, the results shows that the nonlocal friction law is feasible and reliable. |
