Shanghai Lingang Ice and Snow Star is located in Nanhui New City, Shanghai’s New Area. The project employs two types of pile foundations: precast pipe piles and bored cast-in-place piles. In the basement’s general areas, the bottom slab elevation is –7.80 m, with a slab thickness of 700 mm and a leveling layer thickness of 150 mm. In the southeast corner—where the boutique hotel is situated—and in the northeast corner—within the northern resort‑hotel zone—the typical excavation depth is 6.45 m. In certain localized areas of the northwest corner, the typical excavation depth is 7.75 m. Sump pits are 1.50 m deep, elevator shafts are 1.50 m deep, and elevator fire‑fighting sump pits are 3.00 m deep. For the basement area of this excavation, the retaining structure consists of bored cast-in-place piles combined with a single‑row triple‑axis cement‑soil mixing pile cutoff wall, with an internal reinforced concrete support system. The cutoff wall is constructed using ∅850@600 triple‑axis cement‑soil mixing piles. Within the excavation, reinforcement is achieved through 700@500 double‑axis mixing piles supplemented by compaction grouting.
