【摘要】 较长周期波浪对人工护面块体的稳定性有较大影响。通过物理模型试验，系统研究了斜坡堤双联块体的稳定性，分析了波浪深水波陡(周期)、斜坡堤坡度以及谱峰升高因子γ等因素对于双联块体稳定性的影响规律，得到可考虑波浪波陡和谱峰升高因子γ影响的双联块体稳定重量计算公式。研究表明：随着波高增大，双联块体的失稳率也增大；对于同一重量的块体，波陡越小，即相对周期越长，双联块体的失稳波高越小；在相同波陡情况下，谱型越窄，双联块体的失稳波高越小。更多还原

【Abstract】 A systematic physical model test was carried out on the stability of the double-link armor block on the sloping breakwater. The influence of the wave steepness(period), the slope of the breakwater, and the spectral peak factor γ on the stability of the double-link armor block of the sloping breakwater were analyzed. Based on the test results, the formulas for calculating the stable weight of the double-link armor block considering the wave steepness and spectral peak factors γ are derived. The results show that the armor layer damage rate n of the double-link armor block increases as wave height increases. For the double-link armor block with the same weight, the results also show that the wave height that makes the double-link armor block unstable decreases as the wave steepness decreases(the wave period increases). For the double-link armor block with the same wave steepness, narrowing the spectrum type will reduce the wave height, which makes the double-link armor block unstable.更多还原
