The repair of offshore platform jackets is an important research direction in marine engineering, among which the grouting clamp reinforcement is the most widely used. In order to solve the hydrodynamic force of the grouting hoop under the joint action of wave and current in the complex sea condition, the Morison formula is used to analyze the linear wave load on the grouting hoop; then, based on the Morison formula, load force under the combined action of the wave and the ocean current on the clamps in different installation states was determined; finally, the screw jack and car jack were used to carry out the experiment of preventing the clamp from falling off. The mechanical grouting clamp experiment and the wedge tooth experiment were carried out at the same time. The innovative design of the mechanical grouting clamp, analyzed analogously through relevant experimental results and numerical analysis results confirmed that the reinforcement and repair method of the designed grouting clamp is of great help to the safety and reliability of the offshore platform jacket.

波浪和洋流作用下注浆夹的水动力分析与试验研究。

海洋平台外套的修复是海洋工程的重要研究方向，其中灌浆夹箍加固是应用最广泛的。为了解决复杂海况下波浪与水流共同作用下注浆箍的水动力，采用Morison公式对注浆箍的线性波浪荷载进行了分析。然后，根据Morison公式，确定在不同安装状态下，波浪与洋流共同作用的力作用下的夹具力。最后，用螺旋千斤顶和汽车千斤顶进行了防止夹具脱落的实验。同时进行了机械灌浆夹具实验和楔齿实验。机械式灌浆夹具的创新设计，
