Abstract: Based on the Kelvin formula of elastic space solid bearing the concentrating force interiority, the theoretical solutions of the extra-stresses and displacement distribution of the pull-type cable anchorage segment are derived. Subsequently, the distributing formula of shearing stress around the anchorage segment is obtained. Therefore, the influences of mechanical characteristics of the anchorage segment and the rock mass on the extra-stresses, displacements and shearing stresses are discussed. The results show that the field of the normal stresses and displacements around the anchorage segment are tapered. The stresses up the origin of the anchorage segment are compression ones, and those below the origin are tension ones. They are decrease very fast from the origin. The shearing stresses around the anchorage segment form a taper surface and decrease very fast.

Key words: pull-type cable, elastic semi-space theory, theory of anchorage, stress distribution
