| 摘 要： | 斜坡堤护面块体的稳定重力通常按赫德森公式计算,但其安全水平并不明确。提出护面块体安全度的概念,推导出其数值为KN=2.2,两组断面模型试验的结果验证了这个数值是合适的。利用护面块体的安全度,可以客观确定护面块体的稳定重力、新型护面块体的稳定系数,还可用来校验现有各种护面块体稳定系数的合理性。

| Abstract: | The stable weight of armor blocks of sloping breakwaters is calculated by Hudson formula, yet it is indefinite for its safety level. The concept of safety factor for armor blocks and its value of KN=2.2 is given in this paper. Model experiments certify that the value of safety factor is appropriate. The safety factor can be used in determining the stable weight of armor blocks, the coefficient of stability for new-type armor blocks, and in checking the rationality of stability coefficient for all kinds of armor blocks. |
