| 摘要(中) | 本研究以試驗的方法探討阻隔物之材質、管徑、阻隔物的排列方式等因素對水波隔絕的效果，震源產生是以一造波器製造1HZ及2HZ的穩態水波，並量測PVC管、PE管等阻隔物前後方的水波振幅差異性，故試驗是藉由調整5項變數來了解影響阻隔效果的因素，而本試驗全部過程皆在台中港區港灣研究所之室內水工實驗室中進行。 試驗結果顯示PVC材質之阻隔物的管徑參數(C=D/Lw)為0.07~0.43時，其對應的最佳間距參數(S=Sn/Lw)範圍介於0.013~0.14；PE材質之阻隔物的管徑參數C為0.07~0.43時，其對應的最佳間距參數Sn/Lw範圍介於0.02~0.08，若大於最佳淨間距參數則拱效應無法發揮使阻隔有效性驟減。在阻隔物管徑的影響上，相同淨間距下採取管徑參數較大之阻隔物能使震幅降的更低，而產生較佳之阻隔效果。阻隔物的材質探討上，隔震效果較好的有42%是因為使用PE材質的阻隔物，因為阻隔物與波傳介質間的阻抗比IR≠1就能產生阻隔的效果，而且差異越懸殊得到的隔震效果越顯著。 | |||
| 摘要(英) | This research is an
experimental program to steady the barriers effectiveness of hollow
cylindrical piles on steady in coming water waves from a water wave
generation machine. The machine can produce water wave with a frequency
up to 2HZ and an amplitude up to about 3 cm. In the steady﹐the experimental parameters include barriers materials﹐diameter﹐spacing and the array arrangement of the hollow piles. The experiments in the steady wave conducted﹐in the hydraulics experiment station of the department of Transportation in Taichung harbor﹐Taiwan. The results of the tests revealed that﹐in general﹐the PE piles have better barrier effectiveness than PVC piles. The results also indicated that﹐with the diameter parameter C(C=D/Lw) in the range from 0.07 to 0.43﹐the piles exhibit the most optimal barrier effectiveness when the spacing parameters S(Sn/Lw) are in the range from 0.013 to 0.14 for the used PVC piles﹐and from 0.02 to 0.08 for the used PE piles. For both piles﹐the barrier effectiveness significantly decreases when S is larger than the afore-mentioned optimal spacing. Also﹐for the same spacing parameter S﹐piles with larger diameter exhibit better barrier effectiveness. | |||
