| Abstract: | The north channel bridge of Hangzhou Bay Sea-Crossing Bridge is a steel box girder cable-stayed bridge with two diamond-shape pylons and double cable planes.In conformity to the navigational design requirements for the bridge, the ship collision protection devices must be provided at the at bases of the bridge pylons.In this paper,a combined structure of the ship collision protection device and pylon base construction steel boxed cofferdam proposed for the bridge is presented with the aim of providing reference for the design of the protection devices for similar bridge works. |
