摘　　要：基于有限元分析方法,通过Fortran编程实现了粘弹性人工边界在ABAQUS模型中的施加以及基于粘弹性人工边界剪切波的波动输入,研究了斜入射剪切波作用下波的入射方向和振动方向变化以及基础形状参数改变对形状不规则筏板基础摇摆响应的影响。计算结果表明:基础的摇摆响应随着剪切波入射方向和振动方向的改变而变化;斜入射剪切波作用下,不规则基础的摇摆响应会随着基础形状参数的改变而变化,其变化规律同时受到剪切波入射方向和振动方向的影响。Based on finite element analysis method,the viscous-spring artificial boundary and the wave input method of shear waves is implemented into the ABAQUS model through Fortran programming.The influence of the incident and vibration direction of obliquely incident shear waves on the rocking response of the irregularly shaped raft foundations is studied.The results show that the rocking response of the foundation changes with the incident and vibration direction of the shear waves.The rocking response of irregularly shaped foundation to obliquely incident shear waves varies with the shape parameters of the foundation,and the change is also related to the vibration direction of the incident waves.
