Field Test of Self-bearing Pre-stressed Anchor Cable

Abstract:

Self-bearing pre-stressed anchor cable is a kind of tension and pressure compound pre-stressed anchor cable, which can be locked by tensioning without grouting, and is suitable for the rapid anchoring engineering construction of the landslide disaster emergency rescue. Combined with field test data, this paper analyzes the integral tension and anchor cable stress distribution laws of the self-bearing pre-stressed anchor cable and compares this cable with common tensile anchor cable, it is shown that the self-bearing pre-stressed anchor cable not only has the characteristics of rapid anchoring without grouting, but also has uniform stress distribution in anchorage section to fully play the anchoring function in the whole anchoring section, which reflects the advantages of this new type of pre-stressed anchor cable.

Key words:self-bearing; pre-stressed anchor cable; stress distribution; rapid anchoring; emergency rescue
