Article Preview

A series of mechanical properties tests on the supporting body of anchorage cable of late model were carried out, with the forms of the supporting body structure in the anchorage segment of pressure-type anchorage cable, and the strength of surrounding rock in the anchorage segment varied. Those were aimed to study the transfer mechanism of acting forces between the supporting body in the anchorage segment of anchorage cable with pressure uniform and the bearing mortar. Those could be used to gain the distribution and magnitude of axial stress and shear stress of the supporting body, as well as the resisting shear performance of the bearing mortar. The reasonable structure of supporting body of anchorage cable with the pressure uniform could be determined by the tests results. The research showed that the axial stress is distributed with uniform linear form along the steel pipe radius of supporting body with the pressure uniform. The rib—like structure on the surface of the supporting body could improve the resisting shear properties of the bearing mortar and raise the anchorage force 0f the anchorage cable with the pressure uniform. The tests results could be used to optimize the length of the anchorage segment.
