摘要:赣深六标 6-3 路基工程施工过程中,因边坡开挖后存在局部坍塌的问题,因此对边坡采取下部抗滑桩上部
锚杆框架梁组合模式进行防护。 本文以该工程为例,围绕边坡防护锚杆抗拔试验展开研究,在明确试验目的和设
备的基础上,结合以往施工经验及相关专业知识确定合理的施工方案,经过构件受力计算可知结果满足要求,并
简要探讨了锚杆施工的几个要点,最终保证了该工程的整体质量。

Abstract:During the construction of Ganshen Six Bid 6-3 subgrade engineering,due to the local collapse after
excavation of the slope,the slope was protected by the combination mode of lower anti-slide pile and upper an-
chor frame this project as an example,the article carried out research around the pull-out test of the
slope protection anchor rod,based on the clear test purpose and equipment,combined with previous construction
experience and relevant professional knowledge,a reasonable construction plan was determined,the
