摘　　要：以实际工程为背景,得出了有限次数的循环压力注浆可大幅度提高锚杆的有效抗拔锚固力,有效解决了目前锚固结构常用的"一次单向压浆法"锚固力较低的固有缺陷技术难题。In this paper,based on the actual engineering,the research conclusion that the limited number of cyclic pressure grouting can greatly improve the effective anti pulling anchor force of anchor bolt is obtained,which effectively solves the technical problem of low anchorage force of"one-way grouting method"which is commonly used in anchorage structure.

关 键 词：锚固工程 有限循环压力 注浆技术
