摘　　要：能量桩是一种将地源热泵技术和传统桩基相结合的新型桩基。与传统桩基不同,能量桩工作时需同时承担上部建筑荷载和桩体温度变化的影响。目前,国内外学者对于桩体温度变化对能量桩工作特性影响的研究主要集中在温度对能量桩承载特性的影响和对桩土接触面力学特性的影响两个方面。在前人研究的基础上对能量桩的研究现状进行综合阐述,并提出能量桩的未来研究方向。The energy pile is a new type of pile foundation which combines ground source heat pump technology with traditional pile foundation.Different from the traditional pile foundation,the energy pile needs to bear the influence of the upper building load and the temperature change of the pile body at the same time when it works.At present,domestic and foreign scholars’research on the influence of temperature change on the working characteristics of the energy pile mainly focuses on the influence of temperature on the bearing characteristics of the energy pile and the mechanical characteristics of pile-soil interface.On the basis of previous studies,this paper comprehensively expounds the research status of energy piles,and puts forward the future research direction of energy piles.
