摘　　要：为了深入了解变截面桩的变形及承载特性,本文通过系统的理论分析和试验研究,探讨了变截面桩在不同荷载条件下的性能表现。首先选择模型桩材料,设计加载装置。分别完成变截面桩竖向变形与承载特性分析、横向变形与承载特性分析。研究结果表明,变截面桩具有较好的承载能力和变形适应性,能够显著提高桩基工程的稳定性和安全性。通过合理的变径位置设置和优化设计,可以进一步发挥变截面桩的优势。In order to gain a deeper understanding of the deformation and bearing characteristics of variable cross-section piles,this paper explores the performance of variable cross-section piles under different load conditions through systematic theoretical analysis and experimental research.Firstly,the material of the model pile was selected and the loading device was designed.The analysis of vertical deformation and bearing characteristics of variable cross-section piles,as well as the analysis of lateral deformation and bearing characteristics were completed respectively.The research results indicate that variable cross-section piles have good bearing capacity and deformation adaptability,which can significantly improve the stability and safety of pile foundation engineering.By setting reasonable variable diameter positions and optimizing design,the advantages of variable cross-section piles can be further utilized.
