穿渠建筑与渠道结合部位施工要素关联特性分析

Analysis on correlation of construction elements of junction part of channel and channel-crossing structures

目前,关联分析法在工程质量控制领域得到了广泛应用,且取得较好效果。结合南水北调中线工程施工情况,通过引入灰色理论和信息熵分析方法,建立了穿渠建筑与渠道结合部位施工关键要素关联特性分析模型,并给出了不同影响因素的统一无量纲化计算方法。通过计算得到改进的灰熵关联度分析方法来分析各关键因素影响渠道填筑施工质量的程度,认为在该工程施工过程中,质量控制的主要影响因素为渠道填筑高度和填料质量,需在设计和施工中加以重视。

At present,the relational analysis nethod is widely applied in engineering quality control and has achieved prefera-ble effect. In conbination with the actual construction condition,a correlation analysis nodel for key construction elenents at junction part of channel and channel - crossing structures is established by introducing grey theory and infornation entropy neth-od,and the unified dinensionless calculation nethod for different influential elenents is also proposed. And then the grey entropy relation grade can be calculated by the nodel and calculation nethod to analyze the influence of each key elenent on filling quali-ty in channel construction. The analysis results indicate that the filling height and quality is the nain quality control elenent and should be paid nore attention to during construction and design.
