Analysis of lateral bearing mechanism of large-diameter rock-socketed monopile for offshore wind turbine
摘要
Abstract
In view of the large number of rock-socketed demand of offshore wind power foundation in China,horizontal loading characteristics and pile-rock integrated failure mode of large diameter rock-socketed 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 rock-socketed depth on the horizontal bearing capacity of rock-socketed 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 rock-socketed 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 rock-socketed pile is found to improve the horizontal bearing capacity of rock-socketed pile.Pile diameter and overburden thickness have little effect on critical depth of rock-socketed pile,while bedrock strength is sensitive to its change.关键词
