Research on the Optimization Design of the Bridge Foundation Bored Piles

This paper improves the method of calculating the vertical bearing capacity of bored piles, and unifies calculation method of singe pile under horizontal force, as well adds and modifies the design parameters of the specification, finally utilizes actual example to make a unified test of the above methods. The results proved that, through the optimization of bridge foundation design method of bored piles, it can significantly reduce construction cost, and makes the pile length, pile diameter, and reinforcement more safe and reasonable. At the same time, it has great directive significance to the design and construction of the bridge.
