摘　　要：针对我国铁路建设过程中出现的复杂地质和特殊工况问题,铁路建设者提出了各种新工艺新工法,随之而来的挑战是测定新型工艺工法的补充定额,以便完善铁路工程造价体系。如何提高定额数据的准确性和定额测定的稳健性是铁路造价人员需要解决的问题。本文运用误差理论和数理分析的方法,通过建立系统误差、粗大误差和随机误差数据处理模型,对现场测定数据进行计算分析和降噪处理,准确剔除了异常值,提高了定额测定工作的技术高度和深度。In response to the complex geological conditions and special working situations encountered in railway construction in China,constructors have introduced various innovative techniques and methods.A subsequent challenge lies in determining supplementary quotas for these novel processes to refine the cost estimation system for railway engineering.The issue at hand for railway cost estimators is enhancing the accuracy of quota data and the robustness of quota measurement.This paper employed error theory and mathematical analysis methodologies to establish models for handling systematic errors,gross errors,and random errors.By applying these models to compute,analyze,and denoise field measurement data,abnormal values were precisely identified and excluded,thereby elevating the technical rigor and depth of quota measurement.
