Bearing Mechanism and Optimization Methods of Extra-long Group Pile Foundation in Soft Ground
This paper built a theoretical model of 3x3 group piles which can analyze and calculate the single-pile settlement,pile interaction,group pile settlement,and internal force,to study the influencing law of pile diameter,pile length,pile spacing,and different positions of pile foundation on the bearing characteristics of group pile foundation.The optimization design method for the extra-long group pile foundation in the soft ground was proposed,which could theoretically solve the problem of the uneven force of each pile in group piles.
