[0002] A bridge generally refers to a structure built across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. To adapt to the modern rapidly developing transportation industry, bridges are also extended to buildings that are built to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of an upper structure, a lower mechanism, supports, and ancillary structures. The upper mechanism is also called the span mechanism, which is the main mechanism for crossing obstacles. The lower mechanism includes abutments, piers, and foundations. The supports are force transmission devices installed at the supporting locations of the span mechanism and piers or abutments.
