Abstract
In the construction of "One Axis and Four Pavilions" in Shanghai Expo Garden, the concept of "constructing green buildings, and developing low-carbon economy" was demonstrated in the design in view of actual conditions of the pavilions, local soft soil environment, hot summer and cold winter. The design promoted the development of green buildings in China.
Keywords Shanghai Expo Garden, Low-carbon economy, Green building
Construction of Shanghai Expo Garden perfectly demonstrates the theme of "better city, better life", highlights the harmonious coexistence of "man, city and earth", and stresses the responsibility of green building in environmental changes. By introducing sustainable development concepts into the technology platform dominated by green building technology, the Expo Garden realizes the concepts through renovation of building technology, and also achieves the fundamental objectives of harmonious society.
In the planning and design of permanent green buildings in Shanghai Expo Garden- "One Axis and Four Pavilions", the following five principles were fully demonstrated, i.e. resource economy and lower cost principle, pleasant design principle, flexible principle, unification of traditional features and modern technologies. Among the successful green energy-saving, land-saving, water-saving, material-saving and environment-protection technology, comprehensive utilization technology of underground space and green building technology contribute the most to the construction of Shanghai Expo Garden (Fig.l), which is of high demonstration value in soft-soil regions and regions with hot summer and cold winter.

1.1 Analysis of architectural structure, geological structure and environmental characteristics
In terms of planar layout, "One Axis and Four Pavilions" is the symbolic building complex in the core location of Shanghai Expo Garden. To realize the "land-saving" objectives of green building, it is important to use underground spaces comprehensively. "One Axis and Four Pavilions", the permanent buildings in Shanghai Expo Garden, has the Expo Axis as the traffic hub, the large-scale underground complex connects China Pavilion, Theme Pavilion, Expo Center, and Performance Center, rail transit Line 7 and 8, and it is also a major entrance to the garden and a three-dimensional pedestrian traffic hub. The large-scale underground complex of the Expo Axis consists of 2 underground floors and 2 aboveground floors, floor area of the underground space achieves 190,000 m , and the foundation ditch depth ranges from 10 m...
