Abstract: The shear strength and the safety factor of the landslip thrust in the evaluation of the landslip stabilization and the ralculation of the landslip thrust are the very important factors. How to select above data is proposed combined with engineering practice in this paper. And the strurtures retaining the landslips, such as the retaining wall with reinforcements the box foundation bel w the building and the retaining wall supporting the building, are introduced in this paper.
