螺旋桩基础动力响应及抗震研究进展

Research Progress on Dynamic Response and Seismic Resistance of Helical Pile Foundations

为了全面了解螺旋桩在抗震领域的应用及其研究现状,采用CiteSpace软件分对知网和WOS数据库中相关文献进行了量化分析。研究发现:1)试验方面,早期的研究者大多通过现场试验研究螺旋桩的水平和横向振动动力响应,此后,学者们通过振动台试验研究螺旋桩的地震响应。2)理论方面,国外学者多采用数值计算和振动台试验相结合的方式研究其动力性能;国内学者则主要在螺旋桩的水平振动和垂直振动方面进行研究。3)数值模拟方面则主要通过OpenSees等数值模拟软件进行研究。此外,本文还讨论了螺旋桩抗震性能的最新研究进展、存在的问题,以及未来研究的看法和建议。

In order to comprehensively understand the application and research status of helical piles in the field of seismic resistance,the software CiteSpace was used to analyze relevant literature in CNKI and WOS databases.The conclusions are as follows:1)in terms of testing,early researchers studied the horizontal and lateral dynamic responses of helical piles through field experiments.After that,scholars studied the seismic response of helical piles through shaking table tests.2)in terms of theory,most foreign scholars use a combination of numerical calculations and shaking table tests to study the dynamic performance;domestic scholars mainly focus on the horizontal vibration and vertical vibrations of helical piles.3)in terms of numerical simulation,the research is mainly conducted through numerical simulation software such as OpenSees.In addition,the latest research progress,existing problems,opinions and suggestions for future research on the seismic performance of helical piles were discussed.
