摘要:
将基于总应力法的波致土体剪切破坏准则与基于有效应力法的液化准则相结合,对东海大桥海上风电场海床稳定性进行了分析,讨论了平均波高、百年一遇波高及破碎波高3种波况下,场地土体有效正应力、振荡正应力及应力角等值线的变化情况,得到了波高对海床稳定性的影响。结果表明:该方法可为海上风电场的选址及基础设计提供参考。
Abstract:
According to the wave-induced soil shear failure criterion based on the total stress method and the liquefaction criterion based on the effective stress method, authors analyzed the seabed stability of offshore wind farm for Donghai Bridge, and discussed effective normal stress, oscillating normal stress and stress angle contours of the soil under three wave conditions, namely, mean wave height, once-in-a-century wave height and breaking wave height, and the influence of wave height on the seabed stability was obtained. Results show that the method can provide reference for the foundation design of offshore wind farm and location.
