"cantilever bridge"的定义和意义

What is a "cantilever bridge"?

A cantilever bridge is a type of bridge that is supported on only one end, allowing it to extend outward without additional support underneath. This design features horizontal beams that are anchored at one end and project into space, creating a strong and stable structure. Cantilever bridges are often made from steel or concrete and can span significant distances, making them suitable for roadways and railways. The design allows for a clear space below, which is useful in areas where traditional support pillars may not be feasible. Cantilever bridges are known for their strength and unique architectural appearance.
