Analysis on the Ultimate Pullout Force of Prestressed Cable Based on Nonlinear Mohr Strength Criterion

Abstract:

Based on parabolic Mohr strength criterion and the ultimate equilibrium principle, the ultimate pullout force of prestressed cable is studied. The ultimate pullout force of prestressed cable is related to the rock type, the shapes of rapture surface, grouting pressures and compressive strength of rock, etc. The results show that the grouting pressure increases, the ultimate pullout force of prestressed cable increases also. It can provide theoretical supports for some prestressed cable engineering practices.
