| 摘 要： | 采用间接边界元方法求解了入射平面SV波在层状半空间中沉积谷地周围的散射问题.问题的解答包含自由场和散射场两部分.自由场可由直接刚度法求得,散射场由层状半空间中斜线荷载动力格林函数来模拟.文中以入射平面SV波在基岩上单一土层中沉积谷地周围散射为例研究了土层和沉积谷地周围的影响.结果表明,由于考虑了土层的动力特性,平面SV...

| Abstract: | Diffraction of plane SV waves around an alluvial valley in layered half-space is studied using indirect boundary element method(IBEM).The solution is composed of free-field response and diffraction response.The free-field response can be solved by the direct stiffness method,and the diffraction response can be simulated by the Green's function of distributed load acting on an inclined line in a layered half space.The effect of the soil layer and the alluvial valley on the diffraction of plane SV waves is an... |
