Composite foundation with rigid piles and its properties are introduced in brief.A project example, as
well as the design calculation method of applying it,in superhigh-rise buildings is provided. The differ-
ential settlement is successfully eliminated with varied thickness mattress layer.  Compared with tradi-
tional pile foundation, it has remarkable economic, environmental and social profits.
Keywords:  composite foundation; rigid piles; high-rise building; varied thickness mattress layer
