摘要

单柱式海上风能结构物近年来引起各国的高度重视，德国制定了研究大型单柱式风能结构的计划。基于计划要求，通过对历年一些相关文献的研究分析，建立了新型的实验模型模拟单柱式海上风能结构，同时运用Fe程序进行了模拟，共同对砂土中单桩在循环力作用下土体中孔隙水压力变化进行了研究，并对不同渗透率砂土和不同频率的循环力条件下的土体孔隙水压力作了对比分析。得出了土体中孔隙水压力的存在和其存在的大小是受自身和周边条件影响的。此研究结果对于德国大型单柱式风能结构物的研究有一定价值。

Abstract

Recently

many countries have highlighted the single-column offshore-wind structures; and Germany has formulated the plan to research huge single-column offshore-wind energy structures. Based on the plan

Germany sets up new type lab model and uses Fe program to simulate single-column offshore-wind energy structures. All of them are introduced in the paper. The pore water pressure in sandy soil is researched when the single-column is under cyclic load. And then the pore water pressure in different permeabileties of soil and under cyclic load with different frequencies are analyzed. It is concluded that the existence and size of the pore water pressure is influenced by itself and circumstance situation. The research results can be used to research huge single-column offshore-wind energy structures in Germany.
