中文摘要：

FRP包裹钢筋（MFRP）锚杆是在FRP锚杆的基础上,增加钢筋层和功能梯度层达到综合FRP锚杆和钢筋锚杆优点的目的。在界面力学模型基础上,建立三维锚杆拉拔试验有限元模型,通过设置接触单元对锚杆在混凝土中拉拔过程进行模拟。首先对钢锚杆进行了拉拔试验的测试,证明本文方法的可行性。然后将方法运用到FRP包裹钢筋（MFRP）锚杆上,通过不同直径和不同锚固长度的锚杆进行测试,得到一些可供参考的结论,评估MFRP拉拔水工试验的可行性。

英文摘要：

MFRP（Metal Fiber Reinforced Plastics）anchor synthesizes the advantages of steel anchor and FRP anchor. A 3D finite element model was built for anchor pull-out test based on the interface mechanics model, and a series of numerical experiments of reinforcing anchor and FRP anchor were simulated based on the calculation interface model and damage criterion, and then the feasibility of the method was checked by contrast physics experiments. The numerical method will be applied to the FRP wrapped re- bar, and reached some significant reference conclusion.
