Abstract: The location of the slip surface and its shear strength parameters can be determined by using limit equilibrium method and transfer function with implicit solution with a relatively high accuracy. Considering the slip locations relatively close to the railroad alignment, the mitigation measures used both temporary solutions such as sealing off cracks and back surcharge at the toe of slip and long-term solutions such as permanent anti-slip caissons and drainage ditches at the mouth of the stable valley. It is approved that the mitigation measures are safe and effective.
