Abstract

The bridge design is informed by geological data from the Liuquan Medium Bridge on Rongwu Highway and encompasses scheme selection, structural analysis for both the superstructure, as well as a focused study on maintenance and repair strategies. Major components of the design include : 1. Design Criteria : The bridge is designed to accommodate Class I Highway Loads and features two lanes. The seismic design falls under category B, with a foundation layer composed of silty clay. 2. Scheme Evaluation : Several bridge structure alternatives were evaluated, such as the open spandrel arch type, the prestressed hollow slab design, and the simply supported beam bridge utilizing reinforced concrete. Following a thorough comparison, the reinforced concrete beam bridge was determined to be most effective and suitable choice. 3. Structural Design and Analysis : The T-beam cross-sectional form is adopted for the superstructure configuration. The design process encompasses vertical alignment planning, the calculation of critical design parameters through lateral load distribution coefficients and laod combination effect, as well as a systematic arrangement of reinforcement bars. Structural analysis was conducted to assess internal forces acting on the main beams, followed by validation of flexural strength, shear resistance, and deflection compliance. Furthermore, the design integrates thorough calculations related to diaphragm placement, reinforcement detailing, and surface layer continuity. 4. Special Research : A software application utilizing deep learning algorithms has been developed to facilitate the detection of surface cracks on bridge decks. By automating the crack detection process, this technology significantly improves the precision and effectiveness of maintenance activities. Keywords : Highway bridges Simply Supported T-beam, Superstructure, internal force calculation, AutoCAD.
