MENDEZ-SANCHEZ, Arturo F.; PEREZ-TREJO, Leonor; SANCHEZ-CRUZ, Patricia  e  PANIAGUA MERCADO, Ana Ma.. Determination of yield stresses for landslide-vulnerable soils due to rain. Bol. Soc. Geol. Mex [online]. 2011, vol.63, n.2, pp. 345-352. ISSN 1405-3322.

Yield stress as a function of water content for soils prone to debris flows due to rain is studied in this work. Yield stress is calculated by the slump test in cylindrical geometry by using the relation proposed by Pashias et al. (1996). The advantage of using this method is the quick and easy determination of yield stress. In this case, the test can be done in situ in the zone susceptible to debris flows. Results of yield stress variation as a function of water content are shown for the cerro de Xico zone located in Chalco Valley in México State, which is considered to be vulnerable to landslides by the local authorities.

Palavras-chave : Yield stress; debris flows; slump test.
