| Abstract: | The constitutive model of hardened soil is established,and the numerical calculation parameters are selected according to the soil conditions of soft soil area in Jiangsu province.PLAXIS 2D software is used to simulate the horizontal and vertical loading of small-scale prefabricated pile,and the distribution of bending moment along the length of pile and the load displacement curve are obtained.The distribution characteristics of bending moment of small-scale prefabricated pile foundation are analyzed,and the bearing characteristics under the horizontal and vertical loads are explored,which can provide some information for the design and calculation of small-scale prefabricated pile foundation basis of reference. |
