摘　　要：淮河入海水道大运河立交地涵洞身段常年在水下,洞身段日常检查较为困难。为实现深水环境中地涵缺陷快捷、准确和安全的检测要求,研究提出采用水下无人潜航器搭载水下光学摄像头,结合水下图像声呐、全向成像声呐等多参数传感器等,查明涵洞内部淤积情况及混凝土表观是否存在缺陷,采用水下回弹法检测结合水下取芯等方法查明涵洞混凝土强度的整套涵洞工程安全诊断技术,为地涵开展水下检查提供可借鉴的方法和参考。The culvert at Grand Canal Interchange is underwater all year round,and the routine inspection of the culvert is a difficult problem.In order to meet the requirements of rapid,accurate and safe detection of earth culvert defects in deep water environment,an underwater optical camera mounted on an unmanned underwater vehicle(UAV)is proposed in this paper,combined with multi-parameter sensors such as underwater image sonar,omnidirectional image sonar and so on,it is found out whether there is any defect in the internal siltation of culvert and the surface appearance of concrete,a whole set of safety diagnosis methods for culvert engineering are adopted to find out the strength of culvert concrete by using the method of underwater rebound and the method of underwater coring,which can provide a reference for the underwater inspection of culverts.
