Abstract: The theoretical aspects of the soldier piles with ground anchors in the landslide remediation, especially under the seismic conditions, are not explicitly explained and are left behind the practical applications. The current practice does not have a rational and reliable method for the determination for the required length of ground anchors. This paper present a method for selecting the length of the ground anchors under certain subsurface conditions for the landslide remediation projects. The numerical analysis under seismic conditions was performed using FLAC3D and the results were consistent with the observed data.
