Impact of Simulated Harbor Dredging on the Structure and Bank Slope of High-pile Wharf Based on FLAC3 D Software
Based on the dredging project of a wharf basin in an inland river,this paper uses FLAC3 D software to establish a three-dimensional model,analyzes and studies the displacement and stress changes of each wharf component and bank slope before and after dredging.The re-sults show that the dredging project will have an important impact on the displacement and stress of some components of the wharf.After the dredging is completed,a large settlement occurs at the connection position between the wharf and the revetment,which is about 28 mm.The maxi-mum horizontal displacement occurred at the position of the inclined pile section of the wharf,which is about 4 mm.Directly below the longitudinal beam of the approach bridge,the maximum horizontal deformation of the soil layer in the area is about 70 mm.With the increase of the dis-tance between the south end of the wharf and the approach bridge,the supporting effect of the pile foundation gradually weakens,and the lateral deformation of the bridge gradually increases.At the same time,the maximum bending moment and maximum shear force appear at the posi-tion of the pile behind the approach bridge.
