Research on the Deformation Mechanism of High Fill Roadbed in Highways
In order to accurately grasp the deformation mechanism of Highway High Fill Subgrade and provide technical support for highway construction and subsequent operation,based on the survey results of a highway high fill subgrade project,this paper analyzes the slope failure mode and deformation mechanism of high fill subgrade,and proves that if the treatment effect of high fill subgrade base is not good,the slope is prone to slip along the slope toe.After the corresponding treatment scheme of high fill subgrade base is proposed,the finite element software is used to calculate the high fill subgrade section,and the settlement deformation,lateral deformation and other indicators of high fill subgrade are analyzed.Finally,through the on-site monitoring results and finite element analysis data,the paper gives suggestions on the base treat-ment,filling materials,construction technology and other aspects of high fill subgrade,which provides a reliable technical reference for the de-sign and construction of subsequent similar projects.
