基于有限元分析的某高速公路涵洞回填适宜性评价

Evaluation of Suitability for Backfilling of Culvert in an Expressway Culvert Based on Finite Element Analysis

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。

The finite element analysis method is used to evaluate the stress and settlement of the base after backfilling an expressway culvert as well as the settlement of the expressway roadbed and pavement and driving safety.The evaluation results show that it is basically feasible to use the scheme of C20 concrete to backfill and close the culvert,which has the limited impact on the expressway engineering and gives the detailed suggestions for backfilling construction of culverts.
