Bridge Safety Monitoring The Research And Development Of Early Warning Systems

The destroyed bridges made people pay more attention on the quality and use life of these bridges. How to inspect the quality of bridge structure and monitor its safety has become one of the hottest subjects among academics at home and abroad. In recent years, many countries have been work on the bridge which completed or are being conducted, and are doing exploration work in this area. Many large bridges at home and abroad have been or are about to use various types of safety and health monitoring system to ensure the safe use and extend life expectancy. According to the structural safety of large-span cable-stayed bridge monitoring the characteristics of the sensor layout, data acquisition and transmission methods of research, data collection and transmission to seek the best solutions, improve accuracy of data collection and transmission speed. Using neural networks, genetic algorithms to establish authenticity judgment Massive Data Acquisition Analysis Model; establish temperature, wind and wind direction, and other environmental factors on the impact of bridge safety monitoring model function, which is studying the data analysis methods; establish quantifiable levels of injury and the corresponding damage assessment model of the bridge to make reasonable assessment of the status quo, so as to achieve the safety of the bridge structure monitoring and early-warning and assessment.
