摘要
Abstract
To study the static characteristics of PHC cap foundation,the WTG foundation of an offshore wind farm in Vietnam is taken as an example.Based on the common domestic norms and standards,nonlinear finite element theory is used to simulate the nonlinear interaction between pile and soil with nonlinear spring,and the Morison equation is used to calculate the wave load.The WTG foundation of PHC pile cap has been calculated and analyzed.The vibration frequency of the PHC pile high pile cap foundation can avoid the limit range of natural vibration frequency for the WTG when the arrangement is reasonable.And all indexes of PHC pile high pile cap foundation scheme meet the requirements of current specifications and standards.关键词
