摘要

台灣山坡地災害種類繁多，因為土地利用不慎導致地下水積聚，進而造成超額孔隙水壓力弱化地中潛在不整合面，是眾多災害種類之一種，常見於台灣西部麓山台地間經濟作物施作之坡地。災害治理方面以抽除地下超額孔隙水壓，除去導致不穩定層次致動因子為主要目的。本文以新竹縣新埔太平窩之坡地整治為對象，進行長期之水文觀測與坡地穩定調查，期以集水井施工影響坡地水文變化趨勢為重點進行分析，提供未來相關工程設計之參考。

There are many kinds of slope land disasters in Taiwan. Some unsuitable land use make groundwater distribution in certain situations caused the pore water pressure increasing and many slope sliding. Those usually happen at feet of the mountains and tablelands in western part of Taiwan. Engineering made to avoid these slope failures by discharge groundwater designing, so that can improve the slope stability. This study is aimed to monitor and find out the affects of catch well constructed by long term hydrologic trends change on slope land.
