Abstract

The prestressed anchoring technology is applied extensively to the geotechnical projects. Due to the limitations of conventional prestressed anchorage cable, such as stress concentration on the head of anchor-root and distribution nonuniformity of shear stress, a new pressure-type anchor cable with precast anchor head is proposed. A number of numerical simulations based on FLAC3d are conducted to understand the technology systematically. The results show that the compressive stress concentrated on anchor-root is low; the superposition of axial compressive stress and shear stress in the grouting are not obvious; and the stress distribution is uniform. The new pressure-type anchor cable with precast anchor head can overcome the defects of conventional prestressed anchorage cable effectively and improve the reliability of cable significantly. The result can provide an alternative in selecting anchorage system in geotechnical projects.
