以即将并网发电的乡城水电站引水隧洞固结灌浆工程为研究对象。采用以地质雷达为主，声波检测和钻孔压水检测为辅的多种检测手段对多种围岩条件下的引水隧洞固结灌浆工程进行质量检测。通过对雷达检测数据的处理，归纳出缺陷段和密实段固结灌浆雷达检测特征图像，并通过钻孔压水试验和声波检测试验对雷达图像加以验证。结果表明：声波检测结果与地质雷达图像有着一定的联系。而钻孔压水试验得到的透水率与雷达图像没有明显的联系。在综合考虑了检测结果后，初步提出地质雷达检测固结灌浆的质量标准：检测抽样段长度应不少于总长度的5％；衬砌背后无空洞现象；不密实段长度占检测段长度比率小于15％，且位置分布不集中。凡符合上述要求，灌浆质量可评为合格。

The paper took the consolidation grouting project of diversion tunnel at Xiangcheng hydropower sta -tion which will be the grid generation as research object .It mainly used geological radar , and assisted acoustic detection and borehole water pressure detection to detect the consolidation grouting project of diversion tunnel in the condition of a variety of surrounding rock .Through the treatment of radar detected data , the paper sum-marized the characteristic of image of the defect and density section of consolidation grouting of radar detec -tion,and verified the radar image through the tests of borehole water pressure and acoustic detection .The re-sult detected by acoustic wave has certain relation with the image of geological radar .The permeability rate gotten by the test of borehole water pressure has no clear link radar image .This paper presented the quality standards of consolidation grouting project by geological radar detection after comprehensively considering test result .The standards are that sampling length should be not less than 5%of the total length ,there is no empty phenomenon behind the lining .The grouting quality that is in accordance with the above requirements can be evaluated as qualified .
