Abstract：Based on the force balance of anchorage segment，the distribution functions of shear stress and axial force of anchorage segment of pressure-type cable，which are hyperbolic functions，are derived utilizing perfect elastoplastic load-transfer model and the displacement mode of interaction between grout mass，cable and anchorage mass. Based on the above analysis，the influences of different parameters on the stress distribution of the anchorage segment are discussed. These influential factors are prestress and axial stiffness of anchorage segment. Conclusions can be drawn as follows：(1) when the prestress is bigger，the anchorage affect is greater，but the prestress must be in the limitation of the allowable load that the anchorage segment can be borne. (2) the axial stiffness EA is a synthetically factor. Analytical shows that EA increases the effective diameter and the elastic modulus of the anchorage segment physically，which can improve the anchorage effect. These significant results can provide theoretical references for design and calculation of the pressure-type cable.
