摘要
高填方路基自重大,地基处治或施工质量控制不当会使道路结构产生较大沉降,对道路运行状况和行车安全造成较大影响。结合工程项目,采用有限元软件建立模型进行数值模拟分析,对不同施工阶段高填方路基的沉降进行计算。数值模拟计算结果与现场监测结果十分接近,模拟计算结果准确,可用于指导现场施工。
High-fill roadbed has a significant self-weight,and improper foundation treatment or construction quality control can cause significant settlement of the road structure,which has a significant impact on the road operation and driving safety.In combination with the engineering project,thenumerical simulation analysis is made by using the finite element software to establish the model and the settlement of high-fill roadbed at different construction stages is calculated.The numerical simulation calculation results are very close to the on-site monitoring results,and the simulation calculation results are accurate,which can be used to guide the on-site construction.
