Determination of the Failure Surface Geometry in Quick Slides Using Balanced Cross Section Techniques - Application to Aznalcóllar Tailings Dam Failure
Abstract
In a landslide investigation, the location of the failure surface is a difficult task when measures of subsurface displacement are lacking, as it occurs in old landslides or in recent but quick ones. The subsurface geological data and ground surface displacement data may not be enough to formulate a unique interpretation of the failure surface. However, an accurate determination of the failure surface is possible when balanced cross section techniques are applied to preliminary interpretations. The former is proved by means of the example of Aznalcóllar dam failure (Seville, Spain).
