摘要
桥墩冲深计算是桥墩设计中的一个重要方面,而其本身受众多因素影响。目前争议较多的是水深因子的作用。根据试验现象和观测数据等对水深因子的作用进行了研究,得出了冲深随水深的变化是一种多值关系,依据该结论可解释过去多种有争议的观点。并且。
The calculation of scour depth around piers is influenced by many factrs and much controvery is about the effect of flow depth.In the paper,an investigation is made on the effect of flow depth by studying experimental phenomena and observation data.It is believed that the relationship between the flow depth and scour depth is as that of multi numerical value. Thus the controversy in the past can be explained.Similar relationship is also obtained in scour mechanism of spur dikes.
