| 沖擊回波法檢測預(yù)應(yīng)力孔道灌漿質(zhì)量技術(shù)研究(50 卷) |
| 英文標題 |
| Technology Research on Grout Quality Testing in Prestressed Ducts with Impact-Echo Method |
| 摘要 |
| 介紹了沖擊回波法的基本原理，以及其在預(yù)應(yīng)力孔道灌漿質(zhì)量檢測方面的應(yīng)用。利用沖擊回波法對某橋橫向預(yù)應(yīng)力孔道灌漿質(zhì)量進行現(xiàn)場檢測，檢測結(jié)果與工程實際情況相符合，可見沖擊回波法可用于預(yù)應(yīng)力孔道灌漿質(zhì)量檢測，并且能清晰地判別出無預(yù)應(yīng)力孔道（放樣異常）、有預(yù)應(yīng)力孔 |
