Abstract: In order to further make theoretical study on the anchoring mechanism of pressure-type cable，Mindlin basic solution was referenced that concentrated load was on a semi-infinite body inside，and the approximate solution to normal stress and shear stress in anchoring segment grout of pressure-type cable were derived under the circular uniformly distributed load.On this basis，anchor hole radius，bear plate radius，and Poisson′s ratio on the compressive stress of grout and the shear stress of the contact surface were analyzed.The results showed that：anchor hole radius，bear plate radius had a greater impact，Poisson′s ratio was less affected.The contents of the cable anchoring mechanism were enriched further and the theoretical reference for cable design was provided by the research.
