Uso del ángulo de vuelco en la predicción temporal de desprendimientos de rocas

Abstract

On December 3, 2013 occurred the biggest rockfall ever recorded in the pilot study area of Puigcercós scarp (Lleida, Catalonia) since the start of LiDAR monitoring on November 2007. This event, with a volume of 1093 m3, was characterized by a combined fall of four areas affected by toppling failure mechanism. In this work the use of the evolution of toppling angles to temporal prediction of toppling failures is evaluated. Thus, a correct interval of most probably days for rockfall occurrence in three of the four detached areas have been estimated. In conclusion, the use of toppling angle data in this kind of failures are more reliable to temporal prediction that the superficial displacement data.
