摘要

震害调查表明，多次破坏性地震中均发生液化场地桩基严重破坏的典型实例。针对地震土体液化诱发桩基破坏这一突出难题，国内外学者围绕液化场地桩基抗震的紧迫需求，采用多重研究方法，揭示液化场地桩基弯曲、屈曲和沉降等多种失效模式，取得系列丰硕研究成果。首先开展典型液化场地桩基震害实例的调研与分析，总结液化场地桩基震害主要的表现形式和破坏模式，剖析各种桩基失效模式触发机制和演化机制，指出当前研究的重难点问题，并给出液化场地桩基抗震研究进一步需要努力的方向。期望这项工作能够给研究者们提供一些有用的参考，并助力于我国液化场地桩基抗震理论的不断发展和完善。

Abstract

The investigation of earthquake damage shows that the pile foundation in liquefiable soils has been severely damaged in many destructive earthquakes. In view of the prominent problem of pile foundation disaster induced by soil liquefaction

many scholars have adopted multiple research methods to explore the earthquake damage mechanism of pile foundation in liquefiable soils

aiming to meet the urgent need of aseismic design of pile foundation in liquefiable soils. And they have obtained fruitful and important research results

revealing the failure modes of pile foundation in liquefiable soils

such as bending failure

buckling failure and settlement failure. This study surveys and analyzes the typical cases of pile foundation earthquake damage in liquefiable soils

and summarizes the manifestations and failure types of pile foundation earthquake damage. On this basis

the paper dissects progress of different earthquake failure mechanisms of pile foundation

and points out the key and difficult points in the current research. Finally

the insufficiency and challenges of seismic research on pile foundation in liquefiable soils are revealed

and the further research directions are given. This work can provide some useful reference for the researchers

and it is beneficial to the development and perfection of seismic theory of pile foundation in liquefiable soils.
