| 摘要(中) | 摘要 隨著經濟發展，人們改善生活品質，許多都會區進行污水管埋設等工程。由於地下管線埋設複雜，若能掌握維生管線正確的埋設位置，污水工程之進行可儘量避免造成地下管線之破壞。 本研究之目的，利用透地雷達探測道路內地下管線之埋設位置，本研究分別採用100 MHz、250 MHz以及500 MHz之MaLa透地雷達天線頻率，配合RAMAC Ground Vision解析軟體，在卵礫石土層中科污水管工程，已有明挖試坑資料的路段進行現地試驗、影像蒐集，找出較高辨識率之雷達影像，並針對試驗路段管線埋設位置與影像進行比較。 由本研究結果顯示：(1)地下管線區域的影像訊號會產生『倒V』波形的特徵。(2)混凝土包覆電信管群區域，下方訊號會受到混凝土影響而產生明顯的較平緩波狀；混凝土包覆電力管群，下方的波形受到『強電』的影響而有更深的平緩波狀影像訊號。(3)排水箱涵受到箱涵結構體和中間部份灌溉水相異材質之影響，產生『正V』狀的波形影像特徵。(4)不同天線頻率有其適用性，地下管線及箱涵可搭配天線頻率100 MHz和250 MHz相互使用。(5) DC濾波加上Automatic gain control之濾波方式埋設物下方之影像特徵較明顯；而DC濾波加上水平濾波之濾波方式則埋設物上方的影像特徵較清楚。 |

Abstract Due to the living quality have improved following the economy develop, therefore the underground utilities have been constructed in many metropolitian areas. This complicated installation of underground utilities, if we can know the precise locations of their, we will avoid to destroy in the sewage pipe construction today. The goal of research, the locations of underground utilities are explored by using ground penetration radar 100 MHz, 250 MHz and 500 MHz with RAMAC Ground Vision software have been used in this study. In the sewage pipe construction of gravel formation, some excavation pits and GPR images collection have been done, then compare the locations of underground utilities and GPR images. Research results show that:(1) Image amplitude have produced inverted 『V』wave shape in the underground utilities. (2) Under concrete telecommunication circuit area, which amplitude is affected by concrete will produce obvious smooth wave shape. If under concrete electricity area, which amplitude is produced further smooth wave shape. (3) Dewater box is affected by box construction and middle-part irrigation water, then produced the 『V』wave shape. (4) Different antenna frequency have different using, underground utilities or dewater box can use antenna frequency 100 MHz with 250 MHz. (5) The lower image of buring objects of DC filter with Automatic gain control is obvious; otherwise, the upper image of buring objects of DC filter with subtract mean trace is more clear. |
