| 摘 要： | 利用曹妃甸附近海域2006年夏季实测水文泥沙资料,就目前国内应用较为广泛的6种挟沙力计算公式在曹妃甸海域的应用进行比较和分析。结果表明,曹妃甸水域的水流挟沙能力与表征水流强度的弗劳德数相关性较高。同时,综合考虑水流强度和反映紊动作用与重力作用相互对比关系的挟沙力计算公式的精度相对较高。

| Abstract: | Based on the hydrology and sediment data observed around Caofeidian sea area in summer of 2006,calculation methods of sediment carrying capacity in Caofeidian were analyzed with 6 kinds of formulas of sediment carrying capacity which were widely applied in actual coastal engineering.The results show that sediment carrying capacity in Caofeidian has great relativity with Froude number which represents the water intensity.Meanwhile,it is found that the method including both water intensity and the contrastive relationship between turbulence and gravity function is the most accurate. |
