中文摘要：

现有具有代表性的黏结滑移曲线可以分为两大类,一类为单一曲线表达式,另一类为多段表达式。不同的单一表达式黏结滑移曲线变化较大,峰值黏结应力和峰值滑移量均有较大差别;多段表达式明确地表达了上升段、峰值滑移段和残余变形段,不同表达式的峰值应力也有所不同。在比较分析的基础上,提出修正黏结滑移曲线,并采用有限元软件对其进行验证,模拟曲线与参考文献试验曲线符合较好,表明模型和数值模拟的可靠性。

英文摘要：

Sorted out the existing representative bond-slip curves, all of them can be classified as two types, one is the single curve expression, the other is multistage expression, the single bond slip curves changes greatly, peak bond stress and peak slip are quite different.The multistage expressions have three stages:the ascent, peak slip and residual deformation, the peak stress in different expressions are different.On the basis of comparative analysis, a new modified bond-slip curve was proposed and numerical simulation was used to verify the simulation curves, and results showed the reliability of the model.
