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.
Aminated Carbon Nanotubes (CNTs) and Carbon Fiber (CF) materials for anticollision intelligent control of Bridge Engineering were used to enhance the properties of Bismaleimide Resin (BMI) matrix resin and then tested the moist heat aging, salt spray aging and erosion resistance in this study. The resulted show that when the aging time was 168h, after wet heat and salt spray, the flexural strength and impact strength of three-phase composites with 1.5wt% MWNTs-NH2 content can reach maximum, and the wet heat aging bending performance is 45% better than that of non-added carbon nanotubes, the impact performance is 41% higher, the salt spray aging bending performance is 43% higher and the salt spray aging impact performance is 32% higher.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
