摘要

摘要: 针对锚固工程中遇到的动力问题，采用简谐动力波作用下的破坏试验，研究在动力作用下锚杆的锚固机理、锚杆剪应力分布规律及动态抗拔力；结果表明：在动力波作用下剪应力从锚杆端部到底端轮番增大，使锚杆剪应力沿全长均发挥作用，动力作用下抗拔力均比静态经验公式及静态试验结果大。

Abstract: With regard to the dynamic problem in the anchor engineering, a destructive experiment using harmonic seismic waves is designed to analyze anchorage mechanism, shear stress distribution and dynamic pull-out resistence under dymanic load. The results show that the shear stress under dynamic action becomes stronger from the top end to the bottom end of the anchor bolt and play its role along the whole anchor bolt. The pull-out resistence under dynamic action is stronger than the experimental simulation under static situation and experiment.
