Abstract Large deformation cable with constant resistance present super-mechanical characteristics of high constant resistance, large deformation, energy absorption and impact resistance compared to traditional anchor cable. These have been successfully applied in geotechnical engineering and tunnel engineering. In order to effectively solve the technical problems of the cable-stay breaking and the anchor head fall off, due to the large deformation of the traditional reinforcement cable of the slope of the Tonglushan ancient copper mine relics in Daye City, Hubei Province. In this paper, the finite element structure nonlinear analysis model of large deformation cable with constant resistance was established through finite element software ANSYS. Following, combined with the indoor test for comparative analysis, proved the reliability of the numerical simulation Z. Tao (&) Y. Wang M. Li Y. Wang X.

analysis model. Finally, the depth of the potential weak sliding zone (surface) of the slope was determined by the finite element analysis and strength reduction method. This provided a theoretical basis for the construction of deep mechanics monitoring and early warning system based on NPR anchor cable, and realizes the integrated control objectives of the reinforcement, monitoring and early warning of the site slope.

1 Introduction Geological disasters due to landslides are a major type of natural disaster which have a history of affecting human populations. The demand for mineral resources has gradually increased, the height and scale of the slope increased gradually, while the continuous production of industrial and mining enterprises has led to a high number of high and steep slopes, which are highly prone to produce landslides (Andersen and Andersen 2010; Tao et al. 2018a, b). In particular, the collapses caused by open pit mining and landslide disasters severely threaten population and man
