作用在直立桩柱上的破碎波浪力研究

采用理论分析与实验相结合的方法,对现有的计算作用在直立柱体上的破碎波浪力的各种方法(莫里森公式、冲击绕流法)特点进行了分析。提出了计算破碎波浪力的绕流绕流冲击法,并给出了计算实例。结果表明,用绕流绕流冲击法计算出的破碎波浪力比常规波浪力大约3倍,约为冲击绕流法的2倍。实验结果证实了此法的正确性。本研究可为新滩海海洋结构物的设计和现役结构的安全使用提供理论依据。

Breaking wave forces on the vertical cylinders

Breaking wave forces applied to the vertical cylinders were discussed by a method combining the theoretical analysis and experimental verification. The existing methods used for calculating breaking wave forces on the vertical cylinders were introduced. The advantages and disadvantages of these methods were analyzed. The diffraction-diffraction-impact method and the calculation example were given. The results show that the maximum breaking wave force can be about three times larger than the regular wave force and is twice as large as that of the impact-diffraction method if the other conditions are equal. The calculated results are in good accordance with the test results. The research can supply a basis for the design of the new structures and the safe use of the existing structures in very shallow sea.
