| 摘 要： | 针对多项式及约束样条法拟合结果不尽理想的问题,提出了光顺样条算法,应用于桩基内力测试数据处理.以某桩基的滑动测微计的检测应变数据实例,计算了该工程试桩的摩阻力分布规律和极限侧摩阻力.该算法在很大程度上过滤了测量过程中的误差,减少了人为因素的影响,增加了摩阻力计算的可信度.

| Abstract: | The efforts to improve the fitting outcomes of polynomial and controlled spline result in the proposed theory and algorithms of smoothing spline applicable to test data of internal stress of pile foundation.The calculated friction distribution and the limits of lateral friction of the project testing pile come as a result of practical examples of internal strain testing data of sliding micrometer in engineering pile.The algorithms allow the errors occuring in the process of measurement to be filtered to a l... |
