摘要

台北盆地的地下水資源於民國初年極為豐富，地下水位甚至高出地面。隨著台北都會之發展，人口成長與用水量增加等因素，大量鑿井抽水使地下水位急速下降，並導致地盤沉陷。經政府對地下水管制後，地下水位始逐漸回升。本文係研究地下水位回升之趨勢，與探討其對地下工程之影響，並藉台北捷運施工降水案例之成功經驗，供未來其他工程之參考。

Before the turn of the century the groundwater resource in the Taipei Basin was rich and the water table was even higher than the ground surface. Due to the development of Taipei City, extensive pumping to supply water for the city caused the groundwater pressure drawdown and resulted in excessive ground subsidence. The groundwater table recovered as the pumping activities were restricted in 1960's. This paper provides information on the recovery of groundwater and discusses its effects on the underground construction in the Taipei Basin. Successful dewatering in the Taipei Rapid Transit System Project provides good experience for future design.
