【摘要】 为了提高K₃0试验数据处理的效率和优化数据处理的效果,建立了K₃0试验数据曲线拟合、地基系数计算和曲线修正的数学模型,基于Microsoft OfficeExcel软件,编制了能够自动完成荷载强度与下沉量关系曲线拟合、拟合曲线的修正、拟合曲线及辅助线图表的绘制、地基系数计算等功能的程序。该程序易用性好,只需输入K30试验数据便可得出最终结果;通用性强,当可能对数据处理和曲线拟合造成影响的因素发生变化时,程序会做出动态调整;所得效果完全符合《铁路工程土工试验规程》（TB10102-2010）中对曲线拟合和修正的要求。更多还原

【Abstract】 In order to improve the efficiency of data processing and optimize data processing method for K30 test, this paper establishes a mathematical model for the curve fitting of K30 experimental data, calculation of foundation coefficient and curve correction. Meanwhile, based on Microsoft Excel, it compiles the program that can automatically complete curve fitting for the load strength and the sinkage, curve calibration, charts plotting for the curve and auxiliary lines and calculation of foundation coefficient etc. The program is easy of use, the result is reached simply by entering the K30 test data, and it has good versatility. When the factor that may influence the data processing and the curve fitting has been changed, the program will be adjusted; the effect that the program achieve completely conforms to the request of Code for Soil Test of Railway Engineering (TB10102-2010) on curve fitting and correction.更多还原
