- Abstract
Based on the system investigation and mapping of loess engineering slope protection in the areas of Baoji, Shanxi Province, the prevalent problem of prevention and mitigation failure of anti-sliding retaining wall is studied. In this paper, three anti-sliding retaining wall failure modes, loess mud over wall, shear failure and "retaining wall traveling by ship", are put forward. To analyze the relationship between modes and different mechanisms, the authors conducted a loess soil mechanics test and calculated the landslide thrust using the limit equilibrium mehtod with the Lingnan landslide as an example. The results show that: (1) Both engineering slope cutting and rainfall cause slopes instability. (2) Imperfect slope drainage system, incompact surface soil, rainfall and local existence water depression are the leading cause of loess mud flow disaster. The burial depth of anti-sliding retaining wall foundation is the main reason of retaining wall traveling by ship. (3) Finally, the article discusses how to solve the problem of prevention and mitigation failure of anti-sliding retaining wall of loess engineering slope.
