Design of Collision-Proof Equipments for Non-Navigable Hole of Inland River Bridge
This paper is based on the two model demonstrative project of science and technology of Changsha-Xiangtan highway which are non-navigable piers, which belong to a new extra large bridge in Xiang River. We designed Collision-proof equipment for the piers to prevent the collision between the bridge and ship. Considering the crash conditions of the local actual environment, the design could withstand the collision force created by a Ship loaded with 2000 tons, and plays a certain guiding function, so as to ensure the safety of the bridge. This paper had designed a variety of programs through UG,VPG/LS-DYNA model and simulation software, through comparing, eventually determined the optimal scheme.
