摘要
针对地下圆形衬砌洞室对入射平面SH波的散射问题,采用波函数展开法,研究了不同频率入射波作用下,圆形衬砌洞室散射的三维级数解.结果表明:当入射波所在平面与圆形衬砌洞室Z轴互相垂直时,该级数解退化为半无限二维空间中的结果.级数解为定量研究圆形衬砌洞室对不同入射角度和入射波长下的SH波的散射引起的地震动的影响提供了理论依据.
By using series expansion method, scattering of a underground cylindrical lined cavity subjected to incident plane SH waves was studied and the 3-D series solution was presented. The results of study show that when the plane of incident waves and z-axis of the cavity are perpendicular to one another, the series solution can be reduced to the solution for the cavity in two-dimensional half-space. The series solution can be used to quantitatively analyze the effects of a cylindrical lined cavity subjected to incident SH waves due to varies incident wavelength and angle on the ground motion.
