Comparison of Core Performance Indicators and Cost-Effectiveness Analysis When selecting bearing types for municipal bridges, it is necessary to consider the bridge's span
Material Requirements: Rubber bearings should be made of highly elastic and aging-resistant rubber materials to ensure they do not deform or crack during long-term use.
Cylindrical Structure (Mainly Sand-Cylinder Type)
Shape: Primarily cylindrical (150-300mm diameter) or square (200-400mm side length) shells, composed of an outer shell and a core column. A core column insertion hole is pre-drilled at the top, and a sand-removal hole (10-15mm diameter) is provided at the bottom.
Structural safety is the core objective in the full life cycle management of bridges. As bridges age, they may experience slow but continuous structural deformation due to factors such as traffic loads, environmental erosion, and geological changes. These changes are often difficult to detect through visual observation or regular inspections, and sensor-based automated monitoring systems are becoming an important technical means to ensure the long-term safe operation of bridges.
The bridge structural health monitoring system is an automated monitoring system integrating technologies such as the Internet of Things, sensors, wireless transmission, and cloud computing. By collecting structural and environmental data from key bridge components, the system monitors and analyzes the bridge's operational status and performance in real time. Based on the collected key data, it triggers early warning signals for severe anomalies in special weather conditions, traffic situations, or during bridge operation, providing a basis and guidance for bridge maintenance, repair, and management decisions to ensure the safety of the bridge during operation.
