摘要
文章旨在探讨结构方程模型(SEM)在高速公路质量评估中的应用,通过构建一个科学、合理的评估模型,为提升高速公路质量提供理论与分析工具。文章分析现有质量评估方法的局限性,并详细介绍SEM的基本原理及其在高速公路质量评估中的具体应用。通过对322个调查样本的分析,验证SEM模型的有效性,并揭示影响工程质量的关键因素及其相互关系。文章研究结果表明,材料因素和人员因素是影响高速公路质量的主要因素,且这些因素通过复杂的路径网络相互作用。文章不仅为高速公路质量管理提供科学的决策支持,还提出未来研究方向以进一步提升评估模型的准确性和适用性。
This study explores the application of the Structural Equation Model(SEM)in assessing the quality of expressways by constructing a scientifically sound and rational evaluation framework.The proposed model provides both theoretical insights and analytical tools to support quality improvement efforts in expressway construction.The paper critically reviews the limitations of existing quality assessment methods and presents a detailed explanation of the fundamental principles of SEM and its specific application in expressway quality evaluation.Using data from 322 survey samples,the SEM model is validated and used to identify key influencing factors and their interrelationships.The results indicate that material and personnel factors are the most significant contributors to expressway quality,and these variables interact through a complex network of causal paths.This research not only offers a data-driven decision support system for expressway quality management but also outlines future research directions aimed at enhancing the accuracy,robustness,and applicability of the assessment model.
