摘要
以某海域海上风机吸力桶基础为研究对象,采用Abaqus有限元数值模拟软件,考虑基础在不同土层中由水流冲刷导致其周围土体缺失时吸力桶基础的水平承载力.结果表明,桶内土体的缺失对吸力桶水平承载力的影响不大,随着吸力桶基础外周围土体缺失的扩大,其水平承载力逐渐降低,影响海上风机的正常使用.
Abstract
Taken the suction bucket foundation of an offshore fan in a sea area as the research object,the horizontal bearing capacity of the suction bucket foundation is studied by Abaqus finite element numerical simulation software when the soil around the foundation is lost due to the influence of water flow in different soil layers.The results show that the loss of soil in the bucket is of little effect on the horizontal bearing capacity of the suction bucket,and the horizontal bearing capacity of the suction bucket foundation decreases gradually with the expansion of surrounding soil loss,which affects the normal use of the offshore fan.
