Bearing capacity analysis of offshore wind power deepwater screw pile jacket foundation
摘要
Abstract
This paper intends to design a deep water spiral pile jacket foundation structure for offshore wind power,and use finite element analysis to simulate the load of wind,wave,current,wind turbine,and the bearing capacity and stability of the foundation structure under the conditions of silt and silty soil,and provide a feasible reference for the design of the finite element model of pile-soil interaction of spiral pile structure.This paper also designs a common pile control foundation model without helical blade structure by means of lateral comparison,and explores the influence of single helical blade on the bearing capacity and stability of the foundation structure.The research shows that the addition of single-layer helical twist blade structure can significantly improve the bearing capacity and stability of offshore wind power pile foundation structure,and has little influence on the natural vibration frequency under the constraint state of the foundation structure.The relevant data can provide suggestions and references for the design of helical pile foundation in practical engineering.关键词
