In anti-slide structures with continuous ladders (hereinafter referred to as ASCLs), horizontal and vertical reinforced concrete anti-slide members are connected head-to-tail in a ladder-like configuration, positioned along the sliding surfaces of slopes. The anti-slide members are interconnected and anchored from the sliding mass through the sliding zone into the underlying intact bedrock, so as to resist the landslide thrust and replace the weak materials within the sliding zone. By improving the load arrangement, the structural stress of the horizontal anti-slide members, and landslide thrust calculation of ASCLs, numerical extreme values of the axial force, shear force and bending moment were verified in a reasonable numerical range via the extreme values of the analytical and modified analytical results. The extreme value of the axial force of the modified analytical calculation result was between the analytical and numerical results. The maximum modified analytical calculation result of the shear force was between the analytical and numerical results, and the minimum modified analytical calculation result of the shear force was relatively close to the analytical and numerical results. The extreme modified analytical calculation result of the bending moment of the ASCLs was between the analytical and numerical results. The correctness of the numerical calculation results was well verified via the analytical and modified analytical results.
