夹片群锚的锚固性能研究及设计原则

THE ANALYSIS OF MECHANICS AND THE PRINCIPLE OF DESIGN ABOUT THE ANCHORAGE DEVICE WITH CLAMPING PIECES

通过对夹片锚锚具组装件在张拉锚固各个阶段的锚固受力性能进行分析，提出了夹片锚设计除尺寸满足强度要求、尽量小巧外尚应遵循的几条原则。这些原则对改进夹片锚的设计、节省锚具材料、改善锚具组装件性能等都具有积极的指导意义。

This paper analyses the mechanics characteristic of the anchorage device with clamping piecesduring the stressing and anchor stages. And several principles for anchorage design are proposed.They are helpful to save the material of anchorage and to improve the mechanics characteristic ofhe parts for anchorage device with clamping pieces.
