Abstract: Changsha Ice and Snow World is the project for ecological restoration and utilization of the mine which wasoriginally a cement quarry. Its main building functions are the indoor ski resort and the rooftop open?air water park. Due tothe huge difficulty of construction, it was called one of the " impossible projects" . The project has the characteristics ofcomplex basic conditions, special structural form, large floor span and large load and many restrictions on construction andgeological conditions. The form of mega structure supported on the bottom and the wall of the pit were adopted. Several keyissues and design measures of this special project was introduced, such as the relationship between the main structure andthe bottom and wall of the pit, the design of super?large?span prestressed concrete beams, the structural design of heavy?load steel roof, and the dynamic design adjustments affected by geological conditions. Through the comparison of variousstructural schemes, the application of long?span concrete and steel structure technology, and the close combination ofdesign and construction, the design intention of floating structure over the pit is realized integratly.

Keywords:mine restoration and utilization project; mega structure; stability of rock; super?large?span prestressed concretebeam; heavy?load steel roof structure
