文摘：文章导出了基于双剪屈服准则下的钢筋混凝土圆板和球扁壳的屈服条件，并利用此屈服条件求解了极限荷载。

Focusing on the receiver function variation pattern changing wtih different back azimuths, we introduced different kinds of symmetric systems of seismic anisotropy used often, and summarized some possible causes of anisotropy formation. We show details about how to calculate the response of a stratified anisotropy model with symmetric axis of arbitrary orientation.
