    Abstract: 台灣地狹人稠,由於風力發電機運作時會產生噪音,因此並不適合建造於西部沿岸,必須發展離岸風力發電,而離岸風力發電機於海上必須承受反覆側向載重的作用,例如風力、波浪力等週期性之水平力,因此本研究設計出一套可進行側向載重試驗之設備,並使用鋁製模型樁進行一系列之側向載重試驗,探討模型樁受側向載重作用時基樁-土壤間之互制力學行為。

    ;Taiwan has very high density of population. Because the wind turbines make noise, so it is not suitable for the construction of offshore wind turbines in the western land. It is necessary to develop the offshore wind turbines at the offshore environment. The offshore wind turbines usually subjected to cyclic lateral loadings induced by wind and sea wave. In this research, designs the equipment and plans a series of experiments on a model aluminum pile to discussion the behavior of the pile under lateral load.

    In this research, use Zhunan sand to make the soil of the experiment. Three static load tests were conducted. Two of the test was fixed-end and another test was free-end. Two cyclic load tests were conducted and were fixed end. The number of cycles was one thousand and ten thousand. The mending moment measured by the strain gauges on the pile. Use the regression analysis to calculate the function of the pile deflection and soil resistance. Collecting the pile deflection and soil resistance deduce the p-y curves. Calculated the characteristic parameters of coefficient of subgrade reaction with static load and cyclic load. The load-displacement curves of the pile head were discussed the permanent displacement and the pile secant stiffness under cyclic lateral loads.
