為求以本島的自然能源代替國外進口的非再生能源，因此離岸風機技術發展成為台灣所追求的目標。樁基礎為離岸風機主要採用基礎型式，離岸風機之基樁常年承受風力與波浪造成的側向載重，因此其受側向載重的行為，是設計時主要考量的因素。台灣西海岸為軟弱粉土質砂土層，加上颱風、地震侵襲，導致基樁受側向載重傳遞機制複雜，因此進行基樁側推相關實驗是必須的。為節省實驗成本與時間，本研究利用一原用於CPT標定之標度槽改良的模型基樁測試平台，模擬現地土壤應力狀態，有利於試體壓密時達到Ko狀態；在模型基樁側向加載時，降低試驗的邊界效應。研究利用氣霣法製作乾淨砂(硯港砂)試體，以及霧式霣落法製作麥寮砂試體，並以邊界應力控制標度槽模擬不同的邊界條件，進行長樁模型的側推與側向反覆加載試驗，探討樁土互制反應。

In wind turbine design, the long pile is a general option to provide lateral resistance under lateral loading. However, due to the earthquake and typhoons happen in the weastern coast of Taiwan, the mechanism of lateral load transfer is very complicated. In the study, a stress-controlled calibration chamber used on CPT test was modified to do the lateral loading pile tests, including push-over and cyclic loading tests. For reducing the boundary effect, the lateral stress was calculated by the numerical analyses and applied during the lateral loading tests, also, controlling vertical stress can simulate the stress condition in different depths. A model pile with strain gauges for bending strain measurement is fixed on the bottom of chamber and subjected to lateral loading. The bending moment, soil resistance and deflection calculated from the strain were used to develop the soil-pile interactions. Furthermore, in order to investgate the reactions during cyclic loading, the sine waves with different load amplitude were exerted on the pile head. From the test results, the bending moment and soil resistance will increase with the cycles until the soil-pile interaction becomes stable. Also, the cycle to be stable will decrease with the increase of the vertical stress.
