Research on High Strain Detection Technology for Foundation Piles Based on Improved Measured Curve Fitting Method

为进一步提升传统高应变动测法在检测过程中的可靠性,文章提出一种基于改进实测曲线拟合法的基桩高应变检测方法,改进了桩侧软化模型、桩端阻力模型、土塞模型及材料阻尼模型参数。经敏感性分析和工程实例验证,该方法能较好地完成对土体承载性状的模拟,在基桩高应变检测中的应用具有较强的可靠性。

In order to further improve the reliability of the traditional high strain dynamic detection method in the detection process,this paper proposes a high strain detection method for foundation piles based on the improved measured curve fitting method,which improves the parameters of the pile side softening model,the pile end resistance model,the soil plug model and the material damping model.Through sensitivity analysis and engineering example verification,this method can simulate the bearing behavior of soil well,and has strong reliability in the application of high strain detection of foundation piles.
