The stadium's stand is made up of 68 pieces of reinforced concrete frames circling the stadium center. The height of every frame is different, which is from high to low with the curves of roof of the stadium. The main structures under stress are the huge floor-inclined lattice arch centering (main arch，span 288m) and the lattice arch centering (subordinate arch), which joins with the main arch at one end, other bracing points of which are on the top of concrete column; space grid is provided between the main and subordinate arches, which forms stable space structural system. This paper introduced the pier foundation like a box of the main arch and the foundation of the main structure, the structure selections of the main reinforced concrete frames and the steel roof.Keywords： stadium; complex structure; pier foundation; the huge floor-inclined arch; grid structure
