摘要
为确定海上风机嵌岩桩合理的嵌岩深度,本文应用有限元软件ABAQUS,建立三维有限元模型,通过水平承载力、桩身变形、荷载传递等多种因素进行分析,得出:嵌岩深度达到2倍桩直径后,增加1 m嵌岩深度,水平承载力变化小于3‰,同时桩身内力和桩身变形在数值和规律上不再有明显变化,故认为最佳嵌岩深度为2倍桩径。
To determine the reasonable rock-socketed depth of offshore wind turbine rock-socketed piles,a threedimensional finite element model was established using the finite element software ABAQUS.Through the analysis of factors,such as horizontal bearing capacity,pile deformation,and load transfer,the following results are obtained.Under the condition of rock-socketed depth reaching twice the pile diameter,the change in the horizontal bearing capacity is less than 3‰when the rock-socketed depth continues to increase by 1 m..Meanwhile,there is no significant change in the value and law of the internal force and deformation of the pile body.Therefore,the best rock-socketed depth is two times the pile diameter.
