摘　　要：猴子岩水电站帷幕灌浆质量检测采用了压水试验、全景图像和单孔声波检测等物探方法,在对3种物探方法进行理论分析的基础上,详细介绍了猴子岩水电站帷幕灌浆质量管控要点。大坝及厂区物探检测数据及蓄水后量水堰渗流量监测表明,经过帷幕灌浆后,猴子岩水电站帷幕防渗效果总体较好,大坝及厂区帷幕起到良好的防渗阻水作用。Three kinds of geophysical detection methods of water pressure test, panoramic image and single hole sound wave are used to detect the quality of curtain grouting in Houziyan Hydropower Station. Based on the theoretical analysis of three geophysical detection methods, the key points of curtain grouting quality control for Houziyan Hydropower Station are introduced in detail. The geophysical detection data of dam and powerhouse area and the monitoring data of weir seepage flow after reservoir impoundment indicate that the curtain anti-seepage effect of station is generally better after curtain grouting, and the curtain under dam and powerhouse area has a good anti-seepage and water-blocking effect.
