摘要
提出了三维群桩-承台-墩的一种自振特性分析方法,其计算模型不但将群桩-承台-墩作为三维的整体结构来分析,而且考虑了桩-土的相互作用,同时简化了动力分析中承台的刚性模型。
This paper makes an analysis of natural frequency about the 3 D plie groups plie cap pier.Its computation pattern not only gives an analysis to the 3 D pile groups pile cap pier as a whole,but also considers the internal mutual actions between piles and soil,what's more,it simplifies the rigid model of pile cap in the dynamic analysis,providing basis for the study of the aseismic safety analysis to the whole bridge.
