国内外液化场地的震害实例表明研究桩基的动力响应问题是解决桩基震害的关键,而结构参数对桩基动力响应的影响又是其关键问题所在。本文就液化场地桩土动力相互作用参数敏感性的国内外研究现状就行了总结,提出了目前研究中的不足以及今后需深入研究的问题。
The examples of seismic damage at liquefaction sites at home and abroad show that it is the key to solve the dynamic response of pile foundation to solve the seismic damage of pile foundation. The key problem is the influence of structural parameters on the dynamic response of pile foundation. This paper summarizes the domestic and foreign research status quo of the sensitivity of pile-soil dynamic interaction parameters in liquefaction site, puts forward the problems in the current research and the need for further study in the future.
