水利工程堤防填筑压实质量控制与施工效果探究OA

Based on the embankment construction project of the Guyan River Station in the Second Phase of the Huaihe River Seaward Waterway,a combination of laboratory geotechnical tests and finite element numerical simulations was employed to evaluate the shear strength and permeability coefficients of the embankment fill under varying compaction degrees,thereby determining the optimal compaction degree.Subsequently,coupled calculations for seepage,stability,and deformation of the embankment under multiple water level conditions were conducted.The results indicate that the shear strength of the embankment fill increases approximately linearly with compaction degree,while the permeability coefficient decreases.Under optimal compaction degree conditions,both the safety factor and deformation of the embankment under design flood level and rapid drawdown scenarios meet the corresponding control standards.The measured settlement values during on-site construction show minimal deviation from numerical simulation results.These findings provide references for similar embankment filling projects.
