According to the advantages and disadvantages of pre-stressed anti-floating uplift and partially-bonded pre-stressed anti-floating uplift as well as the application limitation in the world, stress-dispersion pre-stressed uplift with steel and strand cage serial techniques were researched to be applied in an uplift project by rotary drilling. The large tonnage test pile was used on the engineering piles with reasonable stress, low cost and short construction period; the practice proves its good application prospect.
