摘要
以某高速公路高填方涵洞工程为原始模型,应用ANSYS10.0对涵洞填土填筑过程进行了数值模拟,对模拟结果进行了深入分析,阐述了涵洞和涵顶填土施工过程中土压力及沉降量的变化规律,并将涵洞的现场量测数据与数值模拟的结果进行对比与验证,得出了用以指导施工的可信性结论.
Based on the high-filled culvert of a certain expressway,this paper firstly takes this culvert as the original model,and carries out a numerical simulation to its construction by using Ansys10.0.Secondly it deeply analyzes the results of the simulation,and finds out the change patterns of earth pressure and settlement in the filling process.Finally,by comparing the results of the in-site test with those of simulation,it draws a credibility conclusion to provide supervision for construction.
