摘要
采用双折线荷载传递函数,导出了 1 组确定锚杆 p -s 曲线的解析算式,并由此提出了锚杆极限承载力的计算公式。算例分析表明,理论与实测 p - s 曲线符合良好,理论承载力计算公式也能较好地反映实际情况。
The load-transfer mechanism on bolts is one of the two major research interests in anchorage theory. With bilinear load-transfer function, a set of analytical equations for p-s curve calculation is established. The analytical bearing capacity of bolts is presented herein. A case study is then carried out to observe the performance of the p-s curve calculation equations and the analytical bearing capacity formulation with expected satisfactory results.
