Abstract The field tests are performed in the anchorage zone of pressure dispersion anchor cable style and the cables are reclaimed. The stress distribution state on the anchorage zone is observed and the equations of the strain and axial force on the anchorage zone are obtained. Field test and the theoretical analysis both show that the unique structure form is a determinant factor for its credible corrosion protection capability，and its bearing capacity and anchoring characters are entirely better than the traditional tension cable style. Otherwise，this cable style has the reclaimable function that has better problem-solving ability of cable overpass allowable scope and can be extensively used in the city foundation pit reinforcement engineering.
