摘　　要：为了研究地下圆形衬砌洞室在入射平面SV波和Rayleigh波作用下的动应力集中问题,利用波函数展开法,求解出三维条件下的级数解。当衬砌与半空间介质相同时,级数解将退化为无衬砌时的结果。级数解为进一步定量分析衬砌洞室对入射平面SV波和Rayleigh波的动力集中提供了理论基础。Using wave function expansion method,a dynamic stress concentration of an underground cylindrical lined cavern subjected to incident plane SV waves and Rayleigh waves was studied and a three-dimensional series solution is presented in this study.When the lined medium and half-space medium are identical,the series solution can be reduced to that of an unlined cavern.The series solution can be used to quantitatively analyze the dynamic stress concentration of the lined cavern subjected to incident plane SV waves and Rayleigh waves.
