摘要
利用波函数展开法,研究了地下圆形衬砌洞室在入射平面SH波作用下的动应力集中问题,并给出了三维条件下的级数解。当入射波所在平面与洞室截面所在平面的夹角为零时,解答将退化为二维条件下的结果。三维级数解为进一步定量分析衬砌洞室对入射平面SH波的动应力集中提供了理论基础。
By using series expansion method, dynamic stress concentration of an underground cylindrical lined cav- ity subjected to incident plane SH waves was studied and the three-dimensional series solution is presented. When the angle included between incident plane and cavity＇ s section plane closes to zero, the result is reduced to two-di- mensional series solution. The three-dimensional series solution provides a theoretical foundation for further quanti- tative analyisis of dynamic stress concentration of the lined cavity subjected to incident plane SH waves.
