Abstract: Selfregression theory and recursion method were applied to analyzing actual settlement of tunnel arch. By comparison, it was obtained that selfregression could better distinguish data quality and filtrate data.So selfregression theory was more proper for high level project monitoring which required higher precision of data; recursion method with strong anti jamming facility could be applied when there was no need for high quality of related data.

Key words: selfregression theory, recursion method, tunnel arch, settlement, model

摘要： 分别应用自归理论和递归方法,对同一组隧道拱部沉降实测数据进行对比分析。分析表明:自归理论的数据 质量辨识与数据筛选能力强于递归方法,宜于原始数据精度要求较高的、高等级项目监控的数据处理；而递归方法 由于抗干扰性能强,在对参与数据质量没有较高要求时使用,亦不失为一种可行的措施。
