目前，我国在地下结构抗震分析与液化破坏研究中尚存在诸多问题，需要深入研究地下结构的动力响应分析的影响因素：对不同结构截面形式、水平-竖向波共同作用、不同地震波输入。在地震作用下处于可液化场地的拱形结构和矩形结构的受力形式和最不利受力位置；模型分别在竖向波以及横向波单独和共同作用下，孔压比幅值也不相同；不同地震波对结构的受力形式影响不大，却对结构加速度影响十分巨大。这些问题的研究分析对可液化场地下结构在地震作用下的动力响应规律与液化破坏形式具有重要的工程应用价值和意义。

At present, there are many problems still existing in the seismic analysis of underground structure and research of liquefaction failure. They are needed to be investigated further. This paper emphasizes on three factors which effect analysis of dynamic response of the underground structure:different forms of structural section, combinational action of horizontal and vertical wave and inputtingdifferent seismic wave. The stress forms and the most adverse location of arch and rectangular structure in the liquefiable site under seismic activity are addressed. The model is under the attack of transverse waves and longitudinal waves respectively and collectively. And the amplitude of pore pressure ratio is various. Different seismic waves have little influence on the stress forms of structure. But the acceleration of structure varies with different seismic waves remarkably; The research and analysis on above problems have important engineering application value and significance of the dynamic response law and liquefaction failure form of underground structures in liquefiable soil when the earthquake strikes.
