摘要
文中依托某跨江大桥工程,基于其所处地理位置及周边情况,针对该工程在跨越铁路、河流、中心岛屿上下部结构、主跨防撞、耐久性等方面,分析其设计要点,根据工程地质情况及桥梁特性,提出该工程关键结构节点的监测指标,建立了桥梁工程的长效安全监测机制,经过现场实际应用,验证了该设计的经济性与安全性.
Abstract
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.
