摘　　要：RECCO圆环是构成边坡柔性防护网中的环形网的主要构件,为弄清其力学性能,文中对RECCO圆环在两端受拉荷载作用下进行了试验研究和数值模拟分析。在数值计算中采用等效面积法和力的平均分配法对圆环进行了简化处理。计算结果表明,采用力的平均分配法对圆环进行简化计算与试验结果较吻合。并通过理论分析,得出了计算RECCO圆环等效截面半径的方法。RECCO ring is the main component of ring network of slope flexible protecting fence.In order to fully understand its mechanic properties,experimental study and numerical simulation analysis are carried out on RECCO ring under tension force at both ends.The ring is simplified using equivalent area method and average force distribution method in numerical calculation.It is shown that the result from simplified calculation using average force distribution method is the same with the test result.Through theoretical analysis,the method for calculating equivalent sectional radius of RECCO ring is educed.
