Health monitoring and maintenance of highway and bridge

Abstract

In recent years, due to the rapid growth of traffic volume, the use frequency and load of Bridges have been significantly increased, and the service state of the bridge structure has deteriorated sharply. At present, there is no corresponding standard specification for the health monitoring and maintenance of Bridges in China, so the safety, durability and normal performance of Bridges are still the focus of people's attention. This paper summarizes the research results of health monitoring and maintenance at home and abroad, summarizes and analyzes the highway bridge health monitoring and maintenance, and introduces the bridge health monitoring system in China.
