摘要(中)

台灣位在環太平洋地震帶上，是由歐亞大陸板塊和菲律賓海板塊擠壓而隆起的島嶼，板塊運動很頻繁，使台灣有許多斷層帶及地震的發生。地震容易使得都會區與人口集中的市鎮發生大規模的災害，特別是沿著地表斷層跡附近的區域。近年來發生的大地震中，斷層錯動所引起的永久性地表變形，讓在斷層跡上方的結構物造成嚴重的破壞，亦或是使近斷層帶的樁基礎產生旋轉、傾斜、水平位移及垂直位移等情形，進而造成其上部橋梁可能發生落橋之情形。因此對於逆斷層錯動引致覆土層變形及對樁基礎互制之影響是值得研究。
本研究將現地群樁基礎進行離心縮尺，於60g離心重力場下，進行逆斷層錯動之離心模型試驗共四組，其中包含一組自由場及三組將群樁模型放置不同位置處，以瞭解樁基礎通過逆斷層錯動時，基樁受力行為及變形與地表附近產生之變形特性及斷層跡發展。試驗結果顯示：(1)剪裂帶之發展會隨著群樁基礎愈靠近斷層錯動面，剪裂帶的寬度愈窄，當群樁基礎一支基樁在上盤，另一支基樁下盤時，會產生第三條斷層跡。(2)當群樁基礎一支基樁在上盤，另一支基樁在下盤，逆斷層錯動時，會造成在上盤處兩支基樁樁底會向下盤變形，另外靠近上盤之樁帽附近會產生一沉陷區域，並使樁帽產生較大之傾角、垂直位移及水平位移。(3)Test1試驗與Test2試驗量測到之彎矩變化趨勢相同，且軸力之變化趨勢亦幾乎相同。

摘要(英)

Taiwan, which is an island that situated on Circum Pacific Seismic Belt and is extruded by Eurasian plate and Philippine sea plate. There are many faults in Taiwan because the plate movement occurs so frequently. When earthquake occurs, it would damage the crowded cities disastrously, especially in the area on the line of the trail of the faults. According to some earthquake recently, it is observed that the permanent displacement was due to dislocation of the fault and caused severe damage to the con-struction that sit on the trail of the fault. In addition, dislocation of the fault also let the pile foundations rotate, decline, and displace horizontally and vertically if they are set in the near-fault area. What’s more, it may lead to the bridge above near-fault area collapse. Therefore, it is worth discussing that the influences between the interaction of the pile founda-tion and the cover layer deformation caused by the dislocation of the reverse fault.
By using centrifuge to scale down the on-site group piles under 60g gravity field, the centrifugal model experiment is be conducted with four sets to analyze the dislocation of the reverse fault. To know how the pile behaves and deforms when reverse fault dislocation occurs, the test in-cludes one set is for free field and the other three sets are for group piles models on different positions. Furthermore, the experiment can also ob-serve the deformation characteristics near the ground and the develop-ment of the trail of the fault .The experimental results indicate: (1) The closer to the dislocation surface of the fault for the group piles founda-tions, the narrower the shear zone is. It causes the third trail of the fault when one of the group piles is on the upper plate and the other is on the lower plate. (2) If one of the group piles is on the upper plate and the other is on the lower plate when reverse fault dislocating, the bottom of the two piles on the upper plate would deform downwards to the lower plate. There is a settlement area near the pile cap on the upper plate, leading to larger rotation, horizontal displacement and vertical displace-ment. (3) It is observed that the trend of the changes of the bending moment in Test 1 and Test 2 are similar, and so do the changes of the axial force within Test 1 and Test 2.
