What role do piles play in bridge construction?

Piles play a critical role in bridge construction primarily by transferring loads to the soil. They are structural elements that are driven deep into the ground to support the weight of the bridge and its dynamic loads, such as traffic and environmental factors. The capacity of piles to carry and distribute these loads effectively depends on the soil's characteristics and the design of the pile itself.

By anchoring the bridge in stable soil layers, piles ensure that the loads are transferred safely and efficiently into the ground, preventing excessive settlement or movement that could compromise the integrity of the bridge. This load transfer process is vital for the overall stability and durability of the bridge, making it a central focus in bridge engineering and construction practices.
