In order to improve the efficiency of water transport, avoid energy waste and protect the environment of the ocean and river, the protection of large transport vessels is particularly important. With the continuous development of waterway regulation and the continuous improvement of navigation conditions, the number of ships sailing in the Yinzhouhu section is increasing, and the risk of bridges being hit by ships is also gradually increasing. There are two common ways of bridge anti-collision: independent anti-collision system and its own anti-collision system. The former often adopts the form of independent anti-collision pier, which is generally used in the anti-collision area of old bridges, New bridges generally do not use this method, the latter mainly uses the method of improving the structural firmness of piers to achieve anti-collision, which is the most commonly used and more economical anti-collision method at present. In order to select a more reasonable standard of ship impact force and lay out reasonable anti-collision facilities, the anti-collision facilities of left branch main pier (55, 56) and right branch main pier (76, 77) of ZhongKai Yinzhouhu super-large bridge are studied and designed to provide reference for bridge design. |
