The principles of bridge guardrail design mainly include the following aspects

1. Strength and stability: Bridge guardrails need to have sufficient strength and stability to withstand the impact of vehicles and the pressure of pedestrians. Generally speaking, the material selection of the guardrail should take into account its durability and corrosion resistance, such as using strong and durable materials such as steel or cast iron.

2. Fall protection: The primary function of bridge guardrails is to prevent vehicles and pedestrians from accidentally falling onto bridges. The height of the guardrail needs to be considered in the design to ensure that it can effectively block the fall of vehicles and pedestrians and cannot be easily climbed over. .

3. Visual effects and aesthetics: The design of bridge guardrails should also take into account their visual effects and aesthetics. The color and shape of the guardrail should be coordinated with the surrounding environment to avoid disturbing and confusing pedestrians and drivers.

4. Compliance with safety standards and specifications: The design of bridge guardrails must comply with relevant safety standards and specifications, such as national and local traffic safety standards, bridge design specifications, etc. Designers need to consider various safety factors according to specific requirements to ensure the effectiveness and safety of the guardrail.
