| 摘 要： | 为研究路堤下涵洞的沉降特性,对某路堤下涵洞的沉降进行现场监测,并建立有限元计算模型,得出涵洞断面的沉降分布情况,计算结果与工程实测吻合较好.涵洞基础的弹性模量对涵顶沉降的影响最大,当弹性模屠从40 MPa降至5 MPa时,涵顶沉降值增大4.39倍,其他材料的弹性模量对涵顶沉降不敏感.回填土和地基土的泊松比对涵顶沉降值的影响较大.

| Abstract: | In order to study the settlement properties of culvert under embankment,the settlement was monitored in-site,and established FEM model,the results are compared with the experiment data,and agree well with them,settlement distribution of the culvert section was gained from the FEM analysis.Calculation results show that the settlement of culvert is greatly affected by the elastic modulus of the culvert foundation,when the elastic modulus decreases from 40 to 5 MPa,the settlement of culvert increased 4.39 time... |
