摘　　要：基于范数概念计算的灰关联度较常用的基于均值思想计算的灰关联度具有更好的整体接近性,本文将范数灰关联 度分析法引入到灌浆加固工程中,应用于确定影响单位深度吸浆量因素的权重上。计算实例表明,该方法具有较高的准确性 和可操作性,能方便、快捷、较准确地确定影响地基单位吸浆量的因素权重。The grey correlation analysis based on the norm concept provides a better approximation than that based on average values. In this paper, the grey correlation analysis of the norm is used to determine controlling factors that affect the unit grouting absorption capacity in the grouting reinforcement project. Case study results indicate that this method provides an easy, quick and accurate assessment of factor weights affecting the unit grouting absorption capacity.
