1. The design of the railing structure must be safe and reliable, and the railing base should be equipped with anchor bars, whose strength should meet the requirements of national regulations

2. The strength of the railing should meet the requirement that the vehicle collides with the railing at a 15 ° angle at a speed of 80KM/H without falling into the river

3. The shape and color of the railing should be coordinated with the surrounding environment, and landscape design is suitable for important bridges.

5. The vertical load acting on the sidewalk railings and handrails on the bridge should be 1.2KM/m; The horizontal outward load should be 2.5KM/m. Both should be calculated separately.
