Optimization of Construction Design for Huachengdadao Subway Station

A comparison has been made of different construction designs for the Huachengdadao subway station. By analysis of foundation excavation calculation with all borehole data, the anchor pile support design is rejected, while the combined design of sparse pile support and neighboring pile-steel pile support with different segment is brought out with consideration of geological condition. The combined design can reduce the project cost and creates a better economic effect and social effect with guarantee of safety for foundation.
