摘要
为了给客运专线无砟轨道地基稳定性评估提供科学、便捷的工具,基于双曲线法与三点法的基本原理,在分析地基沉降评估系统的数学模型、系统结构、功能的基础上,采用VB语言开发了地基沉降评估系统,实例计算表明:评估系统中双曲线法与三点法两种计算方法获得的预计结果与实测结果基本相同,说明程序是正确的,并通过两个特别点的评估曲线对比,证明了该系统计算结果是可靠的,可以满足工程应用。
In order to provide ballastless foundation stability evaluation on passenger special line with scientific and convenient facilities based on basic principles of hyperbolic curves fitting method and three point method,it analyzes the mathematical model,systematic structure and functions of foundation settlement evaluation system,and develops foundation settlement evaluation system by using VB language.Actual calculation demonstrates that： the predicted result with hyperbolic curves fitting method and three point method in evaluation system is identical to actual survey result,which proves that the program is correct.Through the evaluation curve comparison on two special points,it certifies that the calculation result is reliable with this system.Therefore,it can meet the engineering application.
