Evaluation Method for Construction Process Quality of Expressway Subgrade Based on Grey Theory

摘要:

随着新材料、新工艺、新设备的发展，路基施工技术和质量评价方法也在不断更新，如何及时适应新技术，保持评价方法的先进性和有效性，是一个持续的挑战。为此，选取高速公路路基施工过程质量评价指标，并应用基于冲突性指标相关性的权重分配方法（CRITIC法）计算评价指标权重，提出了结合灰色系统理论和聚类分析方法的高速公路路基施工过程质量评价方法。实践结果表明：按照所提出的方法进行评价时， “优”灰色聚类系数高于0.8，说明该评价方法整体表现达到了“优”的水平，且方法权重系数也更高，说明该方法选取的指标贡献更大，能够获得更好的路基施工过程质量评价结果。

Abstract:

With the development of new materials, new processes and new equipment, the subgrade construction technology and the quality evaluation methods are also constantly updated. How to adapt to new technologies in time and maintain the advancement and effectiveness of evaluation methods is a continuous challenge. Therefore, the quality evaluation indicators of the expressway subgrade construction process are selected, and the weight distribution method (CRITIC method) based on the correlation of conflicting indicators is used to calculate the weights of the evaluation indicators. A quality evaluation method for the construction process of expressway subgrade combining the grey system theory and the cluster analysis method is proposed. The practice results show that when evaluated according to the proposed method, the "excellent" grey clustering coefficient is higher than 0.8, which indicates that the overall performance of this evaluation method has reached an "excellent" level, and the weight coefficient of the method is also higher, which indicates that the selected indicators of this method contribute more and can obtain better quality evaluation results for the subgrade construction process.
