摘　　要：对FLAC2D3.3中的锚杆单元模型进行了修正,使其具备模拟锚杆损伤软化的功能。实例分析表明,修正后的模型可有效模拟大变形巷道锚杆支护的特有规律。It is shown from the in-situ monitoring and laboratory experiments that the declining, function-losing, damaging and softening, are the mechanical characteristics of rock bolts in roadways with large deformation. So the model of bolt element in FLAC3.3, a software, was amended to simulate the process of damaging and softening of rock bolts. The research result has been successfully applied in practical works.
