技術說明

本研究應用透地雷達電磁波波傳理論與電磁特性建立電磁波於邊坡地錨自由端鋼腱腐蝕界面損傷所造成之反射能量、振幅、波形、介電常數、阻抗等電磁波特徵物理參數。實驗內容主要以不同地錨自由端鋼腱腐蝕程度之混凝土試體進行地錨構件功能損失評估，並配合鋼腱加速腐蝕試驗與高頻透地雷達探頭進行掃瞄，並以電磁波訊號特性與電磁波波傳行為之基本理論為基礎，並配合數位影像編碼運算技術，擷取腐蝕生成物之波譜軌跡與反射訊號特徵，建立邊坡地錨自由端鋼腱在混凝土不同界面及鋼腱腐蝕的判讀準則，以非破性方式建立有效、快速、準確客觀之邊坡地錨自由端鋼腱損傷量測技術。 Ground anchors is commonly used to stabilize. Potentially unstrable slopes. The use of steel ground amchors is of ten constrained by onerall durability in placement, and the difficulty in maintaining tendon in the anchor. To ensure public safety and highway users exclude from landslide, it is important to undustand the anchors stability. Previously the anchor construction work, the ruet provention technologies were still under development, and some of the anchors constructed aluning this period have aged and lost their performare, resulting steel tendon corrosion occurs locally where the tendon in tersects a crack in the surrounding grout. This project will offer a new approach to evaluate corrosion of steel tendon of free length anchor by ground penetration radar (GPR). GPRwas used to in spect the corrosion process in anchor, in which the chage of amplitudes, travel time and GPR image profile assoated with the tondon reflections were continuously measwed.
