摘要
马前寨拦河水闸工程底板疑似发生破坏,需要进行水下水工混凝土表面缺陷。为此,采用精密水下回声测深仪和探地雷达两种仪器检测,通过数据分析,了解了混凝土表面缺陷情况,可为类似工程缺陷检测提供参考。
The foundation plate of Maqianzhai River sluice is suspected to be damaged,which requires the surface defect detection of underwater hydraulic concrete.Therefore,two instruments of precision underwater echo sounder and ground penetrating radar（GPR） are adopted in the paper for comprehensive detection.The data after detection is analyzed for understanding concrete surface defects,thereby providing reference for defect detection in similar projects.
