Analysis on bearing capacity reinforcement effect of overlength PHC pipe piles in soft soil areas
During the construction of overlength PHC pipe piles in soft soil areas,there is often a phenomenon of"floating pile"caused by squeezing effect and the illusion of difficulty in penetration caused by excessive pore water pressure,which limits the actual bearing capacity of the piles.The pile is reinforced using static load reaction rapid repressing and different hammering redriving methods.After treatment,the bearing capacity reinforcement effect is verified through high strain method and static load test,and relevant redriving control parameters are obtained through dynamic and static comparative analysis.The results indicate that the combination of hydraulic hammer pile driver and high strain specialized equipment can be used as a means of strengthening the bearing capacity of overlength PHC pipe piles in soft soil areas.
