Study on the Pile-soil Interaction of Large-diameter Piles Under the Wave Loading
Large-diameter pile is the main foundation type of offshore wind power engineering, which needs to withstand the long-term wave loadings. The pile-soil interaction is of great significance to the safety and stability of the foundation. In this study, numerical analyses with a two-dimensional model were employed to simulate the wave loading pile in layered soils. The results revealed that the pile-soil interaction shows a positive correlation with the wave loading, present a reciprocal trend, the displacement ranging from −9.3 mm to 10.7 mm in front of the pile and from −9.7 mm to 10.4 mm behind it, the plastic strain initially arises in the soil proximate to the point of rotation, rather than at the mudline, primarily occurs in the clay layer, gradually progressing from the bottom upward and expanding outward. The soil maximum stress is 23.9 kPa in sand layer, while 15.2 kPa in the clay layer, the stress does not correlate with depth in the clay layer, but significantly influenced by the clay layer's distribution.
