Real-Time Monitoring for Effects of Vibration and Temperature of Construction Site on Steel Assembly Bracing of Foundation Pit

In this paper, a real-time monitoring system—including vibration acceleration sensors, temperature and static dynamic strain sensors—is used to monitor the safety status of steel assembly bracing in practical project. It uses 5G wireless networking technology transmit data cloud server for early warning abnormal changes development trends. Real-time obtained construction site are as inputs finite element model corresponding results numerical simulation compared with from monitoring. can be concluded that: (1) stress caused by environmental is very significant which higher than initial prestress bracing; (2) vertical mainly vehicles not remarkable, however, frequency-weighted support relatively large affect sense engineering technicians on site; (3) combination does bracing.
