【摘要】 提出一种直接利用实测四点弯曲管道试样的载荷 (P)～加载点位移 (Δ)曲线确定碳钢管道的JR 阻力曲线的单试样法 ,对几种管道试样进行的试验结果表明 ,用此方法所得的JR 阻力曲线与用其它方法所得的JR 阻力曲线符合较好更多还原

【Abstract】 A method was given to determine the J R resistance curve of piping according to the load-displacement curve. The results of the experiments on several specimens showed that the J R curve determined by the method was in good agreement with the J R curve determined by other methods.更多还原
