基于有限元分析的某高速公路涵洞回填适宜性评价

摘要:

使用有限元分析方法评估某高速公路涵洞回填后基地应力与沉降、高速公路路基与路面沉降及行车安全性，评估结果表明采取C20混凝土回填封闭涵洞的方案基本可行，对高速公路工程影响有限，并给出了具体的涵洞回填施工建议。

Abstract:

Abstract: Based on the finite element analysis method, this paper evaluates the stress and settlement of the base after backfilling a certain expressway culvert, as well as the settlement of the expressway roadbed and pavement and driving safety. The evaluation results show that the scheme of using C20 concrete backfilling the closed culvert is basically feasible and has limited impact on the expressway project, Specific suggestions for culvert backfilling construction are given.
