［摘要］針對目前裝配式混凝土結構的漿錨搭接灌漿飽滿度缺乏有效的無損檢測技術，以某一裝配式混凝土結構工程為背景，研究基于沖擊回波的無損檢測方法在工程中的應用及測試效果。詳細闡述了沖擊回波法現(xiàn)場檢測某裝配式混凝土工程剪力墻波紋管漿錨搭接節(jié)點灌漿飽滿度的測試過程，分析了三種典型墻體波紋管連接節(jié)點測試結果的頻譜圖和名義厚度圖；通過對頻譜圖、名義厚度圖的分析，以及局部取芯驗證，得出沖擊回波法可準確判斷金屬波紋管內(nèi)灌漿的飽滿度，總體測試結果準確。

Abstract:In view of the lack of effective non-destructive testing technology for grouting quality of grouted and splicing joints in precast concrete structures at present, the application and test effect of non-destructive testing technology based on impact-echo method in a precast concrete structure project were studied. The testing process of grouting quality of grouted and splicing joints of corrugated pipe in shear wall of a precast concrete structure project was described in detail, and the spectrum diagram and nominal thickness diagram of three typical wall corrugated pipe joints were analyzed. Through the analysis of the spectrum diagram and the nominal thickness diagram, as well as the local coring verification, it is concluded that the impact-echo method can accurately determine the grouting quality of metal corrugated pipe, and the overall test results are accurate.
