规则波作用下无顶盖开孔沉箱所受垂直力的实验研究

Experimental Study of Vertical Wave Forces Acting on Perforated Caisson

通过水槽规则波波压力实验,对规则波作用下无顶盖开孔沉箱所受垂直力进行了系统的研究。给出了开孔沉箱所受浮托力及总垂直力与实体沉箱所受浮托力(总垂直力)的比值与消浪室相对宽度、相对水深,开孔率等影响因素的关系,提出了计算无顶盖开孔沉箱垂直力的计算方法,为开孔沉箱的进一步工程应用提供了有价值的结果。

The uplift force on bottom and the total vertical force of regular waves acting on perforated caisson are systematically investigated by experiments in this study. Empirical relationships of the ratio of uplift force and the ratio of total vertical force on perforated caisson to those on solid walls with the influencing factors are given. Furthermore, the results of empirical relationships are also compared with formulas given by Chinese Design Criteria and Takahashi, which may be useful for the real engineering application.
