Pile foundation driveability analysis is very important for pile design. In actual projects

precise pile driveability analyses would prevent the pile from being cut off or damaged when the pile couldn’t drive into the given depth

and could also keep pile bearing capacity not less than design capacity when penetration depth is deeper than the design depth. In order to analyze the pile foundation driveability accurately

this paper studies the sensitive factors which could affect pile foundation driveability analysis. 32 experiments are designed with orthogonal experiment and completed by GRLWEAP; the pile driving analysis results are obtained afterwards. Through the case study of Bohai sea oil field platform project

same conclusions can be drawn on the sensitivity regularity of pile foundation driveability influencing factors. The sensitivity of the factors that influencing pile foundation drivability from large to small is in this particular order: piling energy

geological conditions

pile diameter

pile length

cushion thickness

pile wall thickness

stop-driving time

stop-driving location and the pile section numbers.
