Abstract

In offshore engineering, it’s difficult to obtain undisturbed samples. CPT-based design method of pile has become recommending method. In this paper focusing on offshore pile foundation engineering, the typical CPT-based design methods are introduced. Various design methods are evaluated in respect of friction fatigue, pile loading direction, and the plug ratio of open-ended pile in capacity contribution, and the determination of design parameters. CPT-based design methods in the clay are compared with API method. For the typical stratum in the China East Sea, the monopiles of an offshore wind farm are analysed. The calculated capacities of monopiles with different methods are compared with the measured value, and the reliability of methods are evaluated. At last according to the vertical loading condition of the offshore monopile, reasonable suggestions for the current design methods and parameters determination are given.
