The Method Comparison of Anti-Floating of Reinforced Concrete Slab at Underground Business Street

Abstract:

It’s a good mean to develop underground business street. But at South China, usually the underground water level is higher, while the weight of structures is smaller, so it causes a prominent problem—anti-floating of structures. These cases of failure including both whole anti-floating and partial anti-floating are reported occasionally. To thoroughly solve the problem of anti-floating, the foundation design of underground street structure is particularly important. At present there are two kinds of foundation design scheme of the underground street. The First is raft foundation plus anti-floating anchors, and the second is independent foundation plus waterproof plates. In this paper, according to practical underground business street, two kinds of foundation design scheme are used to calculate the foundation respectively. Conclusion are drawn: by means of raft foundation, the quantity of bars at Column pier is smaller than that by means of independent foundation; the quantity of bars at raft is bigger than that by means of waterproof plates; the quantity of bars at waterproof plate is bigger gained by means of experience coefficient method than that by mean of JCCAD.
