摘　　要：为了掌握岩塞爆破后形成的进水洞及周边的水下情况,发现威胁进水洞正常营运潜在的风险,需对岩塞爆破后的进水洞进行水下检查。针对深水层进水洞水下检查存在的困难,通过分析水下检测技术原理,比较常用水下检测方法的优劣,提出了多波束测深系统扫描联合ROV水下检查的思路,设计了水下联合检测的技术方案,应用于某水库排沙洞工程岩爆后进水洞水下检查,实践验证加工的多波束工作平台和关键技术,对提高水下检查效率和成果精度作用明显,可为类似水下检测项目提供参考。In order to understand the water inlet formed after rock plug blasting and the surrounding underwater conditions,and define potential risks that threaten the normal operation of the water inlet,it is necessary to conduct underwater detection of the water inlet after rock plug blasting.Aiming at the difficulties in underwater detection of deep water inlet,by analyzing the principle of underwater detection technology and comparing the advantages and disadvantages of commonly used underwater detection methods,the idea of multi-beam bathymetry scanning combined with ROV underwater detection is proposed,and the technical scheme of the combined underwater detection is designed and applied to the underwater detection of the water inlet after a rock blasting in a sand flushing works of a reservoir.It is verified in practice that the multi-beam working platform and key technology can significantly increase the underwater detection efficiency and the precision of detection result,which provides a reference for similar underwater detection works.
