摘要
椭圆墩式码头为一种较为新型的墩式码头结构形式,目前水运工程相关规范对大型椭圆墩式码头的波浪力计算等尚不完全适用。基于水运工程规范中墩柱波浪力计算理论,结合工程案例和试验数据进行对比研究。结果表明:1)对于大型椭圆墩式码头,小尺度桩体横向波浪力实测值小于计算值,大尺度墩体纵向波浪力实测值大于计算值。2)对于小尺度桩体,水运规范计算方法不能反映边墩与中墩的波浪力差异,边墩横向波浪力实测值略小于中墩。对于大尺度墩体,规范计算不能充分反映出边墩和中墩的纵向波浪力差异。3)对于重要工程,建议波浪力以物模试验结果为准。
The elliptic pier-type wharf is a relatively new type of wharf structure.At present,the relevant standards of water transportation engineering are not fully applicable to the wave force calculation of large elliptic pier-type wharfs.Based on the calculation theory of wave force on pier and pile in the water transportation engineering code,a comparative study is carried out with engineering cases and test data.The results show that:1)For large-scale elliptic pier,the measured values of small-scale pile transverse wave force are less than the calculated values,and the measured values of large-scale pier longitudinal wave force are greater than the calculated values.2)For small-scale piles,the difference of wave forces between the side pier and the middle pier cannot be reflected by the calculation method of water transport code,and the measured value of the lateral wave forces of the side pier is slightly smaller than that of the middle pier.For large-scale piers,the difference of longitudinal wave forces between side pier and middle pier cannot be fully reflected in the calculation of code.3)For important engineering,it is suggested that the wave force should be determined by the results of physical model test.
