| dc.description.abstract | 水文地層剖析儀(hydrostratigraphic profiling tool, HPT)與氣壓式微水試驗儀(pneumatic slug test, PST) 在國際上近年使用本技術施行與成果顯示為即時、現地推估淺層(<25~30米)含水層垂直水力傳導係數，K(z)，的尖端技術。本技術適用於淺層粒徑小於4 mm之未固結含水層，臺灣地區目前所設置地下水觀測站網獲得水力傳導係數資訊多為深層，如何有效、快速的決定淺層K(z)對含水層補注設計及執行是相當關鍵的因素。二者均與直接貫入(direct-push) 機組搭配使用，無須設井，程序快速。本研究內容包括(1) HPT及PST設備與限制、使用概要與資料分析方法，(2) 於高屏地區潮寮國小、大明國小及昭明國小三個地下水位觀測站施行HPT及PST試驗，獲得不同觀測站淺層含水層之導電度、地層反應壓隨深度變化結果與特定深度的水力傳導係數，經迴歸換算可決定觀測站的K(z)分佈，(3) 彙整HPT及PST研究資料與本研究現場試驗結果製成導電度、地層材料及粒徑大小之關係圖，提供後續研究HPT導電度參考。試驗結果表示利用HPT及PST對於地質材料K值有高辨認性。

| dc.description.abstract | The hydrostratigrapic profiling tool (HPT) and the pneumatic slug tester (PST) are two state-of-the-art technologies for real-time and in-situ determination available for shallow (less than 30 meters) of K(z), unconsolidated materials of grain size smaller than about 4mm. In Taiwan groundwater monitoring network to obtain hydraulic conductivity information for deep of K. How to effectively and rapidly determine K(z) is an important issue in the design and conduction of aquifer recharge. Because they are attached to the direct-push machine, their application requires no well installation and is relatively rapid. In this study include (1) HPT and PST equipment, limiting and data analysis methods, (2) HPT and PST tests at three sites in Southern Taiwan, collecting the vertical variation of electric conductivity and formation response pressure, and depth-specific hydraulic conductivity; regression analysis of them yields K(z) of the test locations, and (3) a chart for electric conductivity of different unconsolidated materials and grain size by making use of literature data and field data collected in this project, and it provides reference for HPT data analysis. The results of this assessment demonstrate that the HPT and PST can provide high-resolution K estimates.
