High-fill Subgrade Deformation Monitoring and Simulation Analysis
In order to study the deformation law of the high-fill subgrade,the simulation analysis is made by using the finite element model,and the monitoring is carried out by arranging the measurement point at the construction site.The calculation result of the model is compared with the on-site monitoring result.The analysis shows that:the settlement in the construction stage of subgrade filling is large,and the settlement growth rate gradually slows down after completion,and finally reaches a stable state.The finite element calculation results of settlement and uplift of each part of the subgrade are close to the on-site monitoring results,and the deformation is small,indicating that the calculation results are accurate and the subgrade structure is stable.
