Analysis of Stress and Deformation Characteristics of Pile Foundation in Coastal Soft Soil Area
The variation of vertical displacement,lateral displacement,axial force and shear force of piles at different sections with the depth of piles is analyzed by means of numerical simulation model.The results show that the vertical displacement of pile on the left side of section 62 does not change with the increase of pile depth.The vertical displacement of piles on the left side of section No.63 and 64 shows a linear increase rule,and the burial depth increases 1 m,the vertical displacement increases 0.000 2 m and 0.000 19 m espectively.The shear force of the pile on the left side increases first(0～15 m),then increases(15～17.5 m)and finally decreases(17.5～21.6 m).The shear force of the middle pile increases first,then decreases and then stabilizes.
