摘　　要：窨井井体模块砖灌芯混凝土密实性无相关检测方法。论文开展了地质雷达探测法在模块砖灌芯混凝土密实性检测中的应用研究。通过试验室模型研究发现,雷达法用于检测模块砖灌芯混凝土密实性的定性分析是可行的。在工程实例中,采用横向扫描和竖向扫描2种交叉综合法进行检测,效果良好。建议窨井相关标准编制过程中,考虑将雷达法引入,以控制模块砖灌芯混凝土的密实性。There was no relevant test method for the compactness of grouted concrete of manhole module brick.In this paper,the application of GPR detection method in the compactness detection for grouted concrete of manhole module brick was studied.Through the laboratory model study,it was found that the radar method was feasible to detect the qualitative analysis of the compactness for grouted concrete of manhole module brick.In an engineering example,two cross synthesis methods of horizontal scanning and vertical scanning were used for detection,and the effect was good.It was suggested that the radar method should be introduced into the compilation of relevant standards for manhole to control the compactness grouted concrete of module brick.
