摘    要:利用饱和土层的精确动力刚度矩阵和动力格林(Green)函数,采用间接边界元法,在频域内求解了层状饱和场地中任意凹陷地形对入射SV波的散射问题.通过自由场反应分析,求得凹陷地形表面各点的位移和各单元的应力响应;同样计算了虚拟分布荷载的格林影响函数,求得相应的位移和应力响应;根据边界条件确定虚拟分布荷载,将自由场位移响应和...

Abstract:Based on exact dynamic-stiffness matrices and Green's functions of a layered saturated soil,the scattering of SV waves by a canyon of arbitrary shape in a saturated layered half-space is modeled using the indirect boundary element method in frequency domain.The free-field responses are calculated to determine the displacement and stress at canyon surface,and fictitious distributed loads are then applied on the canyon surface in the free field to calculate the Green's functions for displacement and stress.Th...
Keywords:saturated layered half-space  canyon of arbitrary shape  SV wave  scattering
