【摘要】 本文在系统地总结了国内外学者有关气幕式消波系统研究工作的基础上,在大连理工大学海岸和近海工程国家重点实验室的长22m、宽0．4m、深0．6m的小波浪水槽和长 69m、宽2．0m、深1．8m的大波浪水槽分别进行了模型比尺为1:30、1:15和1:10的物理模型试验,对气幕式防波堤的消浪性能进行了初步分析,并对该消波系统的模型试验相似关系进行了探讨。通过对不同比尺试验中测量的孔管入口处的空气容积流量、透射系数等试验结果进行分析和外推,给出了气幕式消波系统模型试验的近似相似关系。该研究工作对深入了解气幕式消波系统的工作特性和建立其物模试验技术具有重要的意义。更多还原

【Abstract】 Based on the theoretical analysis of air bubbles breakwater and its influence factors, the model test is designed and the model law is explored in the paper. The tests are conducted both in the large wave-current tank and small wave-current tank in the State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology. The air amount required and transmission coefficients are measured in the regular wave action with scales of 1:30, 1:15 and 1:10 respectively. Through the extrapolation of testing results with different scales, the empirical model law of air bubbles breakwater is given. The research work is very informative for further investigation on the behaviors of air bubbles breakwater and the technique of model testing.更多还原
