摘 ? 要：提出了以DL型里氏硬度計作為檢測設備的鋼筋套筒連接灌漿料抗壓強度無損檢測方法，測試了灌漿料試件的表面硬度，并建立了測強曲線。研究結果表明，灌漿料試件的表面硬度基本服從正態分布，前后兩次表面硬度測試結果的重復性較好。試件的表面硬度與抗壓強度具有強正相關性，推薦采用指數回歸方法建立測強曲線，相關系數可達0.945。
Abstract: A non-destructive testing method for the compressive strength of grouting materials for steel sleeves using DL type Leeb hardness tester as a testing device was put forward, and the surface hardness of grouting materials was tested and the strength curve was established. The results show that the surface hardness of grouting materials is normally distributed, and the surface hardness test has good repeatability. The surface hardness of the specimen is strongly correlated with the compressive strength, and it is recommended to use the exponential function regression to establish strength curve, and the correlation coefficient can reach 0.945.
