Abstract：
For the total load caused by the dead weight of the buildings and other external factors is insufficient, in order to balance the buoyancy generated by the groundwater, it must exert vertical force on foundation slab to balance buoyancy, and the anti-uplift anchor bolt just uses its own tensile strength. The pulling force generated by the friction between the anchor rod and the soil layer can restrain the up-floating trend of foundation. Compare to the several construction technology of the anti-uplift anchor, it is found that dry construction has its particular superiority on increasing the cohesion and the compacting effect of the anti-uplift anchor effect，also it is good for cost saving.
