| Abstract: | In this paper,multi-year water depth data observed in the typical platform areas of the Chengdao oil field are analyzed and studied,the scour process and the scour pit pattern and distributions around the platform pile foundation under the actions of tidal current are explored,and two empirical formulas are chosen to calculate the ultimate scour depths around the platform pile foundations.It is shown from the comparison between the caculated results and observed results that the chosen empirical formulas are applicable for the Chengdao sea area. |
