Not far from the estuary, Sutong Yangtze River Bridge is located in the Jiangsu Province of China, the main bridge is a 7-span continuous cable stayed bridge，with the span arrangement of 100+100+300+1088+300+100+100 m. The foundations are cast-in-situ bored piles. One of the critical loads in the design of foundations is ship impact force. According to the actual situation of Sutong Bridge, researches were carried out for the collision between ship and foundations, base on the researches comparison was carried out between floating collision protection system and self-resistant protection system which self-resistant system were proved to be the preferred proposal. The self-resistant system make use of steel cofferdam of casting of pile cap, the thickness of tremie concrete was adjusted according to navigation water level and dimension of typical ships. As part of the collision protection system, introduction was made for the vessel navigation system (VTS).
