Abstract. It often happens in anchor cable projects that the beams of anchor cable fail to exert the optimal effect or even the projects fail due to the irrational design of anchorage angle. In response to this, based on the principal theoretical formula, the expression of the optimal anchorage angle was deduced, taking the bending moment of beams of anchor cable. Relevant software was compiled. The validity of the results was verified. The calculation of the optimal anchorage angle under different theories was also researched to be compared with the results of this paper.

“…For example, Cai and Ugai (2003) used 3D zero-thickness M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT elastoplastic interface elements to simulate the soil-anchor interactions. In this paper, reinforcement of anchor cable is realized by surface loading (Hryciw, 1991), i.e. different distributions of surface loading represent various reinforcement schemes.…”

How to determine reasonable position and length of anchor cable is a frequently encountered but not well addressed problem in slope reinforcement projects. In this paper, the variable-modulus elastoplastic strength reduction method (SRM) is used to obtain the stress field, displacement field, and factor of safety of slope. Slope reinforcement using anchor cables is modeled by surface loading, i.e. different distributions of surface loading represent various reinforcement schemes. Optimal reinforcement scheme of anchor cables can be determined based on slope stress and displacement fields. By comparing the factor of safety and stress field before and after slope reinforcement, it is found that better reinforcement results can be achieved if strong reinforcement is applied upon the regions with high stress and large displacement. This method can well optimize the arrangement of anchor cables. In addition, several cases are employed to verify the proposed method.

“…On the other hand, numerous studies have presented the deterministic methodology of anchor design for slope stabilisation, which has been in use since the 1990s (e.g. Cushing, Withiam, Szwed, & Nowak, 2003; Federal Highway Administration US Department of Transportation [FHWA], 1999;Hryciw, 1991;Zhu, Lee, Chan, & Jiang, 2005). Hryciw (1991) performed a theoretical study to determine the optimum orientation of anchors for stabilisation of slopes by employing the concept of surface loads.…”

In this paper, a methodology using Monte Carlo simulation method was developed in conjunction with the modified limiting equilibrium method of slices. Additionally, the time-dependent deterioration of bond capacity of corroding soil anchors was developed in this methodology due to the attack of chlorides. Uncertainties of anchor-related variables and soil parameters were considered using pertinent statistical descriptors. Furthermore, the inherent stochastic nature of the corrosion and degradation process for the anchor/slope system was identified and incorporated in the simulation. A PC-based software, C-UASLOPE, has been coded to allow for handling of complex slope geometry, soil profile and groundwater conditions. An illustrative example was presented to clarify the application of the C-UASLOPE software in modelling the deterioration process to aid in determining the system reliability. The importance of using a system reliability-based algorithm was illustrated by showing that the anchor/slope system may fail unpredictably during design life -even though the initial design results have a high degree of safety -if uncertainties of soil parameters, anchor force and the time-dependent stochastic corrosion process are not accounted for systematically.
