Finite Element Analysis and Field Monitoring of Settlement of High Fill Subgrade
In order to improve the construction safety of highway high-fill subgrade in mountainous areas,a finite element model was estab-lished by using Abaqus software to analyze the variation law of subgrade settlement under different positions of subgrade and different fillers,and the construction site was monitored.The results show that the settlement of high fill subgrade increases rapidly at first and then slowly with the increase of fill height.The settlement of the subgrade at the calculated point D is the most significant,and the settlement of the subgrade with M1 filler is the largest.In addition,the monitoring value of subgrade settlement is close to the simulated value,which can provide refer-ence for the field construction of high-fill subgrade.
