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 superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles. The substructure includes abutments, piers, and foundations. Supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments. Ancillary structures refer to bridgehead cladding, conical slope protection, bank protection, diversion projects, etc.
