跨江大桥结构设计要点及长效监测系统设计研究OA

Based on the geographical location and surrounding conditions of a cross-river bridge project,this paper analyzes the design key points of the bridge structure in the aspects of crossing railway,river,central island structure,main span collision avoidance,durability,etc.According to the engineering geology and bridge characteristics,the monitoring indicators of the key structural nodes of the project are pro-posed.After practical application on site,and the economy and safety of the design are verified by field construction and long-term monitoring system.The research results can provide reference for similar bridge engineering.
