摘要
Abstract
In this paper,the mid-span closure technology of long-span cable-stayed bridge is studied from two aspects:monitoring method and calculation theory.In terms of monitoring methods,an intelligent monitoring system for real-time monitoring is formed by using multi-data fusion theory.The sensor type and arrangement of mid-span closure are studied,and a common arrangement method is proposed.In the aspect of calculation theory,the leveling process of closure is formulated,which reduces the artificial judgment in the decision-making process,and the calculation process of matching and cutting length of closure section is mathematically simplified.Finally,the feasibility of the method is verified by an engineering example of a sea-crossing bridge.The results show that the method has high field implementability,the error meets the practical requirements of the project,and the construction efficiency of mid-span closure is improved.关键词
