Abstract: In Chengdu，the calculation and design of basement foundation for multi-storey structures are special. Local method adopts single foundations with waterproof boards, which is different from conventional calculation method of JCCAD. The two methods were analyzed and their relation was discussed, and economic comparison of  two different structural anti-floating schemes for a two-storey underground garage was carried out.

Keywords: raft foundation; single foundation with waterproof board; subgrade coefficient; anti-floating anchor
