| Abstract: | By 2-D tidal current mathematical model and calculation results using the code formula,the variety of current and seabed evolution near the bridge and the navigation clearance for secondary navigable spans of the bridge are analyzed and demonstrated after the bridge construction.The results show that adopting two secondary navigable spans on south and north sides respectively of Xiangshan port bridge,the navigation clearance and current conditions of three design plans can meet the navigation requirements for ships with the capacity less than 1 000 dwt.The navigation route can follow the habit before the project builds. |
