摘要: 
目前混凝土非破壞檢測技術大多採用應力波或是超音波當做試驗媒介,透過瑕疵介面之間所造成波的折反射訊號反推求瑕疵位置,但是對於混凝土早期裂紋,甚至因反覆載重疲勞所造成之材料劣化,目前尚無法檢測。D.M. Donskoy以及A.M. Sutin等人在1997年首度透過外加振動(無論是利用敲擊或是另外以低頻超音波導入試體)強迫使裂紋的接觸面積發生改變之後,進而觀察另外一個高頻頻率周圍是否產生調變諧波,將該現象應用在金屬構件的細微裂紋非破壞檢測上,稱之為振動調變法,主動式的振動調變法對於裂縫存在敏感度較高,有助於早期材料破壞之預警。
本研究目的在於將該理論應用在混凝土裂縫瑕疵之非破壞檢測,研究結果顯示,即使材料初期裂紋表面不明顯甚至解壓後閉合,透過主動式振動調變檢測(Vibro-Acoustic Modulation Technique) 導入ω1與ω2兩頻率不同應力波的激發,低頻可使裂紋產生開合效果改變接觸式裂紋的接觸面積,使其產生額外的調變波,而調變波的出現可當作接觸型裂紋存在指標,達成檢測目的。在均質材料鋼試體的效應試驗,可以明顯辨識出若試體中有瑕疵的存在,則調變波便會產生。且導入之低頻與高頻比率約小於0.45%時,其調變波之訊號趨於穩定。再將主動式振動調變技術應用於混凝土材料,當試體中有裂縫時,其導入高頻兩側有調變波的產生。而隨著裂縫深度不同(瑕疵程度不同)時,其調變波之數量及振幅大小會與裂縫深度成正比。因此將主動式振動調變檢測技術應用於混凝土裂縫瑕疵,獲得好的檢測成果。
