| 摘 要： | 针对粉沙质海岸开敞航道的回淤特点提出了一个计算航道回淤的统计概化模型。用此模型计算了某港粉沙质航道在施工过程中遭遇几次大风后的回淤量 ,并用此港实际测量所得回淤量来验证 ,得出较为一致的结果。因而 ,此模型可用于实际工程计算。又通过此港的实际资料 ,进行了粉沙质航道回淤的统计特性分析 ,为进一步开展粉沙质航道泥沙运动和航道回淤研究提供了一些参考资料。

A Statistical Probability Model for Calculating Siltation of Open Channel on a Silt-sandy Beach |
| |
| Abstract: | A Statistical probability model for calculating deposition amount is proposed on the basis of depositing features of the open channel on a silt sandy beach.Deposition amount of the open channel of a harbor due to several times of gale during the construction is calculated with the model.And throngh comparison,the calculated results are in good agreement with that measured from the field.Therefore,it's considered that the model is suitable for constructional calculation.And finally,statistical characteristics of siltation in open channel is analyzed from the field data of the harbor. |
