液化场地上土体侧向变形对桩基影响研究评述

State-of-art of study on influences of liquefaction-induced soil spreading over pile foundation response

总结了地震作用下桩基震害现象以及桩-土-结构动力相互作用、液化引起地面侧向扩展对桩基的影响方面理论模型和分析方法的研究现状,指出了存在的问题,讨论了今后的发展趋势。

The damage phenomenon of pile foundation, the soil-pile-structure dynamical interaction, as well as the theoretical models and analytical methods of pile foundation response due to liquefaction-induced ground lateral spreading under the action of strong earthquakes are summarized in this paper .The existing problems in the field are pointed out, and the trends of future study are discussed.
