摘　　要：通过二维物模试验,对规则波作用下明基床上开孔沉箱所受波浪力进行了较为系统的试验研究。分析了总水平力极值(峰、谷值)时刻对应的总垂直力与其影响因素之间的关系,给出了明基床上开孔沉箱总垂直力比值(总水平力极值时刻对应的总垂直力/总垂直力极值)与各影响因素之间的计算关系式,对开孔沉箱的实际工程应用具有参考意义。Through 2D experiments in the wave flume, systematical study has been done on regular wave acting on perforated caisson sitting on rubble mound foundation. This paper discusses the relationship between the total vertical force when the total horizontal force reaches its peak and the major influencing factors. A simplified method for calculating the ratios of total vertical forces （total vertical force when the total horizontal force reaches its peak/the peak value of total vertical {orces） and their major {actors is proposed, which may be useful for engineering design and application.
