【正文】 evaluate geological conditions of indoor soil test analysis and insitu test . By paring all kinds of foundation reinforcement method and construction process, the CFG pile foundation treatment is chosen . The main contents of design is that the pile length choose 20m and pile diameter select 500mm, single pile bearing force calculation results for 1078kN, pile spacing of and area displacement rate of % and calculation of posite foundation bearing capacity and settlement of the calculus 500kPa. This design can ensure the building safety.
