Design of Retrogressive Landslide Control by Inversion Algorithm and the Construction

Abstract:

The retrogressive landslide was caused by the cutting of highway at K193+060 of national highway 213. After the landslide, it was found that the landslide thrust calculated with mechanical parameters of sliding surface by exploration were inconsistent with practical sliding state. The mechanical parameters of sliding surface should be designed by slope body limit equilibrium method before earth removal, which is inversion algorithm. The paper introduced the main engineering treatment methods and construction technologies.
