Thickness Design of CFG Pile Cushion in Sections with Uneven Soft Soil Thickness
As one of the components of CFG pile soft soil reinforcement technology,the design of cushion layer thickness can effectively ensure the reinforcement effect of CFG pile technology.When CFG pile technology is applied in practice,it is often affected by the dis-tribution of soft soil in the project location.The design thickness of cushion layer is calculated by analyzing the stress diffusion thick-ness of the pile and the thickness of the pile penetrating into the cushion layer,and verified by the bridge engineering case with uneven actual soft soil thickness,The monitoring and simulation methods are used to reflect the best CFG pile cushion thickness according to the change of settlement.Through comparison,the best CFG pile cushion thickness is about 0.5 m,and the calculated cushion design thickness is 0.48 m.The relative error between the two is small.The cushion thickness calculated can meet the use requirements.
