砂土中大型单柱式风能结构物在循环力作用下的研究

Study on Huge Single Column Style Offshore Wind Energy Structure Under Cycle Power

通过对自然界海浪循环力的分析研究,确定了新型的试验模型,并运用了加载试验法确定了试验所需循环力的大小,通过实验,对砂土中大型海上单柱式风能结构在循环力作用下的位移进行了研究。结果表明,Hettler教授所建立的位移公式中的经验参数CN是适合海上风能结构物计算的,砂土中大型海上风能结构在循环力作用下的位移是可预见的,并且单桩在循环力作用下的位移并不受土的形态、类型、密实度及颗粒分配等影响。这对海上风能结构的进一步研究有着重要的理论价值。

The displacement of offshore huge single column wind energy structure under ocean weave circle power is great in nature,. By analysis of ocean weave circle power ,a new test model is set up by the research of ocean circle power in nature, the circle power is fixed through the load test. And by model test, the displacement of huge single column wind generation electricity structure under huge single column wind power structure under circle power is studied. The result shows that the empirical formula for displacement which is set up by professor Hettler is correct. Parameter CN is adapt to displacement model of the wind energy structure under the ocean weave circle power. The displacement has nothing to do with the form ,type, density and distribution of particles of sand, is predictable. The results have value to research of huge single col- umn offshore wind power structures.
