Abstract: More precast piles have been widely used due to its short duration,convenience and reliability of construction etc. While the precast piles are driven into sand clay area,effective stress and soil strength increases with the reduction of pore water pressure due to pile extrusion effect. Meanwhile,the bearing capacity of piles also increases greatly because of sand clay extrusion effect.
