台北捷運北投機廠填土沉陷案例

A Case Study on Earthfill Settlement at Peitou Depot of Taipei Rapid Transit Systems

摘要


北投機廠為台北都會區捷運系統最重要之車輛維修廠,廠區佔地40公頃。地表以下有厚度15~50公尺之低強度、高壓縮性黏土層。因工程需求而於其上填土1.5~5.2公尺,並打設垂直排水帶,以加速沉陷。1990年11月完工後至今,廠區最大沉陷量為1.9公尺,依不同分區,目前仍1.0~2.7mm/月之沉陷速率持續沉陷中。

並列摘要


Peitou depot is the most important maintenance works of Taipei Rapid Transit Systems with an area of forty acres. A clay layer of low strength and high compressibility with a thickness of 15~50 meters is beneath the ground surface. To raise its ground level, an earthfill with a thickness of 1.5~5.2 meters was placed over the clay layer. Vertical drains were installed in the same period of time. After completion of the earthfill in November 1990, the largest settlement within the area has reached 1.9 meters and continues to increase at acurrent rate of 1.0~2.7 mm/month.
