| 直墙式码头前沿护底结构的设置是确保码头主体结构整体安全稳定性的重要措施之一，墙前波浪底流和船舶螺旋桨射流扰动冲刷作用是护底结构设计考虑的两大主要因素。目前，我国现行水运工程设计规范对墙前波浪底流冲刷的护底结构设计思路与方法较为全面，但对于船舶螺旋桨射流引起的冲刷计算及护底结构设计缺少明确的计算方法。对比分析国内外规范关于直墙式码头前沿护底结构设计方面的差异，结合工程实例进行了验算，并与实际检测情况进行对比，说明了滚装码头船舶螺旋桨射流冲刷对基床破坏的严重性及护底结构设计的重要性，以供相关规范标准修订参考。 |

| It is one of the important measures to ensure the overall safety and stability of the main structure of the straight wall wharf,the wave bottom current in front of the wall and the disturbing and scouring action of the propeller jet are two main factors considered in the design of the bottom protection structure.At present,the current design code for water transport engineering in China is comprehensive in the design ideas and methods of bottom protection structure with wave bottom current scouring in front of the wall.However,there is a lack of explicit calculation method for the scour caused by propeller jet and the design of bottom protection structure.This paper compares and analyzes the differences in the design of the front bottom protection structure of the straight wall wharf between the domestic and foreign codes,verifies them with engineering examples,and compares them with actual testing results.It explains the severity of the damage to the foundation bed caused by the jet erosion of the ship propeller in the ro-ro wharf and the importance of the bottom protection structure design,providing reference for the revision of relevant standards and regulations. |
