Outline
In view of the large number of rocksocketed demand of offshore wind power foundation in China, horizontal loading characteristics and pilerock integrated failure mode of large diameter rocksocketed monopile foundation are studied by combining physical model test and numerical simulation method, and the analysis of the influences of bedrock strength, pile foundation diameter, wall thickness and rocksocketed depth on the horizontal bearing capacity of rocksocketed pile is carried out. The research shows that the flexural capacity of pile increases with the increase of bedrock strength. The failure mode of shallow bedrock of rocksocketed pile foundation follows passive wedge failure mode, while the failure mode of deep bedrock follows rotating failure mode. The horizontal bearing capacity of pile foundation can be improved with the increase of bedrock strength, pile diameter and depth of rock socketed, but the pile thickness has little effect on it. Critical depth of rocksocketed pile is found to improve the horizontal bearing capacity of rocksocketed pile. Pile diameter and overburden thickness have little effect on critical depth of rocksocketed pile, while bedrock strength is sensitive to its change.
