A new tension-compression dispersive anchor cable was recently adopted in projects

which is based on the combination of tension

compression and load dispersive anchor cables. However

there is a limited study on the mechanism and design method of the anchor cable. Based on the Kelvin solution

we derived analytical solutions of the shear stress between surrounding rock (soil) and the anchoring segments of the tension-dispersive and compression-dispersive anchor cables

respectively. According to the superposition principle

a simplified calculation method was proposed to obtain the shear stress between anchoring segment and surrounding rock (soil). On the basis of theoretical results

the new anchor cable was applied in practical engineering

and the basic performance test of the anchor cable and the comparison with the prestress loss of the tension-dispersed anchor cable were performed

respectively. Theoretical results indicated that the values of shear stress at both ends of the unit anchoring segment were relatively higher

while the stress reached the lowest in the middle. The distribution characteristics of shear stress were consistent with testing results in the literature and numerical simulation results. According to testing results

i.e.

the bearing capacity of the anchor cable

the peak values of shear stress in tension and compression sections were obtained using the simplified method

which agreed well with peak values of shear stress by means of the uniaxial compressive strength of rock in tension and compression anchor cables. The comparison results and the long-term monitoring data reveal that the effect of engineering application is good

and the load transfer of the anchor cable is stable and reliable.
