摘要
结合承秦高速公路的检测实践,论述了射线正交性、射线密度、单元体数目对桥梁CT成像可靠性和分辨率的影响。结果表明桥梁CT图像直观、位置准确、结果可靠,能满足工程质量控制要求。
Combined with practical test of Chengqin Expressway, influence of ray orthogonality, ray density and element number on reliability and resolution of bridge CT imaging is discussed. The result shows that bridge CT imaging is visualized with accurate position and reliable result, which could meet requirements for project quality control.
