    Abstract: 透地雷達(GPR)對於地下結構具有快速檢測、解析度高及非破壞性探測的優點,適用於地層構造之描繪及地下污染物的偵測。經由GPR施測所得的成果與傳統鑽探或明溝開挖比較後,透地雷達法具有省錢、省時及省力的優勢。本研究即希望以實例來評估透地雷達法應用於地下掩埋廢棄物及DNAPL污染等相關問題的可行性。 研究共分兩個案例,第一部分是針對掩埋場之地層構造及地下掩埋物範圍作偵測,以評估GPR之成效;第二部分是以GPR對地表下之有機化學污染物(DNAPL)作檢測與追蹤監測。此外,GPR的施測成果也將與直流電阻法的RIP(Resistivity Image Profile)測勘作一比較對照。 研究結果證實透地雷達能夠描繪出地層構造與地下掩埋物的範圍。另外,經由三維(3-D)GPR測勘的協助,可將DNAPL移動的路徑正確地描繪出來。 Ground penetrating radar (GPR) has the advantage of quick surveying, high resolution and non-destructive for locating subsurface structures. It is suitable applied to delineate the subsurface structure and detecting contaminants etc. Compared the GPR data to that of the traditional well drilling or trench, GPR method has the advantage of cost effective, time and labor saving. This study is to evaluate the feasibility of GPR applied to the problems related to buried wasters and DNAPL contamination. Two causes are being discussed. First, stress on the geology structures and landfill boundaries in a landfill. Second, detect and monitor the subsurface distribution of dense nonaqueous phase liquid (DNAPL). In addition, the GPR results are also compared to that of RIP resistivity image profile. Based on the demonstration of this study, GPR does capable of mapping the subsurface structure and boundary of the rubbish. In addition, with the aid of three-dimensional (3-D) GPR measurements, the migration of DNAPL can be delineated accuracy.
