摘　　要：为了探究地层冲刷对桥梁桩基础竖向承载力的影响,本文通过介绍试桩概况,详细描述了桩基冲刷数值模拟的过程。首先,建立了桩基模型并设置了桩基与土体的相互作用条件系数;随后,进行了冲刷过程的数值模拟。基于模拟结果,分析了地层冲刷条件下桥梁桩基础的竖向承载特性。此外,通过算例验证分析,进一步证实了研究方法的可靠性。研究结果表明,地层冲刷会显著影响桥梁桩基础的竖向承载力,需要在实际工程中予以充分考虑。这一发现对于提高桥梁结构的稳定性和安全性具有重要意义。In order to explore the influence of geological erosion on the vertical bearing capacity of bridge pile foundations,this article introduces the overview of pile testing and describes in detail the process of numerical simulation of pile foundation erosion.Firstly,a pile foundation model was established and the interaction condition coefficients between the pile foundation and the soil were set;Subsequently,numerical simulations of the erosion process were conducted.Based on simulation results,the vertical bearing characteristics of bridge pile foundations under geological erosion conditions were analyzed.In addition,the reliability of the research method was further confirmed through numerical examples for verification and analysis.The research results indicate that soil erosion significantly affects the vertical bearing capacity of bridge pile foundations,which needs to be fully considered in practical engineering.This discovery is of great significance for improving the stability and safety of bridge structures.
