钢结构施工过程监测数据缺失机理与处理方法

Data Missing Mechanism in Construction Monitoring and Its Treatment

摘要:

分析并总结了钢结构施工过程监测中缺失数据的成因及特征，依据缺失数据形成机制将缺失数据分为三类.根据不同类型和特征的缺失数据，提出了基于最小二乘原理以回归分析理论为基础的数据补偿方法.通过对大同美术馆屋盖钢结构和“生命之环”钢结构施工过程监测数据的分析处理与比较，验证了该方法的有效性，说明了该方法的实用价值.

Abstract:

This paper categorizes the missing data into three kinds by their generating mechanism and characteristics. Data processing and compensation methods are proposed on the basis of the regression analysis by least square method. A comparative study of the monitoring data about the steel structure of Datong Art Gallery in Shanxi Province and “the ring of life” in Shenyang City of Liaoning Province confirms that the proposed methods for missing data treatment are effective and practical.
