| 摘 要： | 利用大型有限元软件ABAQUS所提供的用户单元子程序UEL接口,开发了一种三维锚杆单元.该单元所采用的本构模型可以模拟锚杆初锚、增阻、恒阻、降阻全过程,并考虑了锚杆的横向剪切加固效应.算例分析表明,利用此自开发单元可得出合理的锚固数值分析结果. |

| Abstract: | A 3-D bolt element is developed by using the user element interface in ABAQUS.The constitutive model of the element can simulate the whole process of pre-anchor,resistance increase,resistance maintenance,and resistance decrease;and the reinforcing property of transverse resisting shear is included in the model.The numerical example shows that the reasonable results can be gained by using the 3-D bolt element. |
