Application of Squeezed Branch Pile in Underground Building for Anti-floating Design

Various current anti-floatting measures in the Underground building are analyzed. According to the bearing force character of squeezed branch pile, a new idea that squeezed branch pile is used to anti-floatting pile is suggested. The calculation formula and structure requests are given. The technology of construction for squeezed branch pile is elaborated too. A practical project is analyzed in technique and economy,it shows that it is very economical and reasonable that squeezed branch pile is used to solve the anti-floatting problem of the underground building.
