I. Project Background: Constructing a "Mountain Landscape" Atop Jinan

*Project Name: Jinan Central Business District (Jinan CBD)

*Core Structure: Encompassing five supertall landmark buildings representing "mountains, springs, lakes, rivers, and the city," as well as a ribbon park.

*Technical Challenges:

1. Supertall Building Stress: The tower structures have large height spans, requiring the foundation columns to withstand immense vertical axial forces.

2. Irregular Building Structure: The CBD extensively utilizes complex steel structures such as diagonal spans and torsional structures.

3. Underground Integrated Utility Tunnel: As a model for smart cities, the underground utility network requires extremely high corrosion resistance and lifespan for its materials.
