利用弹性有限元模型有效地分析了在地震作用下的地下结构侧面动土压力的影响因素。本文重点研究了墙体和土体的相对弯曲刚度,对于动土压力等效作用力的大小,以及位置的影响。结果表明墙体对上述的影响大于土体的影响。这一结果为修正地下结构的相对弯矩刚度公式和今后简化动土压力的公式提供了参考。之后研究四种特殊情况发现,刚性结构和硬土的动土压力最大;刚性结构和软土的动土压力最小。

Elastic finite element model is one of the effective analysis of underground structures under earthquake to determine the side earth pressure influence factor.This paper focuses on the wall and the relative flexibility stiffness of the soil,earth pressure resultant force,and the location of application force.The results show that the impact by the wall is greater than the impact by soil.This results provide a reference for correcting the relative underground structure earth pressure formula and simplify the formula for future.In special circumstances,the study have found that rigid structure and the stiff soil is the most affect on dynamic earth pressure;rigid and soft soil of the earth is the minimum dynamic earth pressure.
