Abstract Constant-resistance-large-deformation(CRLD) cables have been widely applied in a large number of slopes for monitoring and reinforcement. In order to analyze the constant resistance of the CRLD cable，it is considered as a thick-walled cylinder problem according to the shape and the dimension of the pipe. Differing from the classical Lame equation and thin-walled cylinder issues，this study took into account the effects of axial and shear stresses，and established a 3-dimensional elasto-plastic analytical model. The 3D analytical model became the Lame equation in 2D under the plane strain assumption. In order to verify this analytical model，static tension tests were performed to 3 samples with different geometric parameters. The experimental results were compared with 2D and 3D analytical models. The calculated results with 3D model was close to the experimental data. The 3D analytical model can be used to estimate the constant resistance of different CRLD cables and for optimal design.

Key words： slope engineering;CRLD cables;energy-absorbing cables;thick-walled cylinder problem;static tension test;3D elasto-plastic analytical model
