Abstract: The design alternative and implementation of foundation treatment project of outdoor venues of China Expro are introduced. The design alternative is based the primary function and stress history of foundation soils and the partition overall consideration of building function. Different subareas are pertinently designed. Treatment methods are desilting, clean surface, back-filling in layers, control of load distribution form for regular service, pre-compaction uniting consolidation and so on. The scene effect is fine. Moreover, the calculated final settlement, total settlement and degree of consolidation analyzed, and they agree with the actual measurement. The rationality of the design alternative and design parameters is thus validated.
