The pseudo - static method ( static method in brief ) is now currently adopted in seismic analysis of retaining structures for some well known limitation 受各种条件限制,挡土墙的抗震验算,仍普遍采用拟静力法(以下简称静力法) 。
The earthquake force was ignored during designing midget pump station , while the pseudo - static method just gave approximate calculation to the large and medium pump station ever 在以往的泵站设计中,对于小型泵站,一般不考虑地震力;对于大中型泵站,即使考虑地震载荷大多都运用拟静力法,进行大致的近似计算。
