| PRESSURE-DISPERSIVE ANTI-FLOAT ANCHOR TECHNIQUE AND ITS APPLICATION TO ENGINEERING |

Abstract Combining a practical case，the technique of pressure dispersive anti-float anchor on experiment，design，construction and examination is studied. The pressure-dispersive anchor，especially the U-shaped anchor surrounding load body has good endurance，high anchor efficiency，and advantage of stress and deformation coordination of the underground structure and reduces the structure-building price. It has obvious technique advantage as the permanent anti-float anchor. Only at design tensile load does each unit of the pressure-dispersive anchor undertake the same tensile load；the identical load and synchronous tension method should be adopted to tension test of pressure-depressive anchor.
