［摘要］结合工程实际设计了预制剪力墙试件和预制夹心保温剪力墙试件，开展了基于X射线数字成像法（DR）的检测技术研究，并和X射线胶片成像法、X射线计算机成像法（CR）进行了对比。研究结果表明：DR检测技术用于预制剪力墙或预制夹心保温剪力墙中单排居中套筒或梅花形布置套筒的灌浆质量的检测是可行的，用于双排对称布置套筒的灌浆质量检测，必要时需要结合破损法进行判别；与胶片成像检测技术和CR检测技术相比，DR检测技术成像更为清晰，在预制剪力墙套筒灌浆连接质量的检测中应用前景十分广阔。

Abstract:Combined with engineering practice, precast shear wall specimens and precast sandwich insulation shear wall specimens were designed, and the inspection technology study was conducted based on the X-ray digital radiography  method(DR), which was compared with the X-ray film radiography method and the X-ray computed radiography method(CR). Study results indicate that: the DR inspection technology is feasible for grouting quality inspection for single row centered sleeves or plum blossom arranged sleeves in precast shear wall or precast sandwich insulation shear wall, but for double row symmetrically arranged sleeves, the destructive inspection method should be combined to judge the grouting quality when necessary; compared with the X-ray film radiography and CR inspection technology, DR inspection technology has clearer imaging effect, which will be widely used in the testing for sleeve grouting connection quality of precast shear wall structure.

Keywords:sleeve grouting connection quality; X-ray digital radiography method; X-ray film radiography method; X-ray computed radiography method
