Abstract

AbstractRock mass strength parameters are critical when applying the permanent-displacement analysis to landslide susceptibility assessment. Previous studies use limited measured data to assign a constant value for each lithology. Since the rock mass strength is spatially heterogeneous, assigning a constant value to each lithology cannot effectively reflect the spatial heterogeneity of rock mass strength, reducing the reliability of seismic landslide susceptibility assessment. Here we present an analysis of a well-documented seismic landslide inventory and the lithological environment, and develop an empirical model to quantify the rock mass strength heterogeneity. The rock mass strength heterogeneity was subsequently taken as an input of the permanent-displacement analysis to assessing regional seismic landslide susceptibility. Results on two case studies show that considering the rock mass strength heterogeneity would significantly improve seismic landslide susceptibility assessment. The findings of this study are valuable for earthquake emergency rescue and post-earthquake land plans.

Abstract

Esta exposición tiene por finalidad ofrecer una síntesis sobre un tipo específico de registro arqueológico: talleres líticos. Estima que el mismo tiene una correlación estructural con el terreno y procura representarla con mapas de relieve y pendiente, otorgando a ésta última un valor de atractor causal para la explotación eco-económica del ambiente por la población prehispánica. Los talleres estudiados se localizan en el sur de la Sierra de Comechingones, en un sector de cordones serranos erosionados con altitud máxima de 1100 m.s.n.m. Se trata de un tipo de registro arqueológico muy numeroso en esta parte de la sierra; se considera al mismo representativo de un modo de producción y una larga tradición tecno-económica por parte de las poblaciones indígenas que colonizaron este paisaje en tiempos prehispánicos. The purpose of this paper is to offer a synthesis on a specific type of archaeological record: lithic workshops. It considers that it has a structural correlation with the land and seeks to represent it with relief and slope maps, giving the latter a causal attractor value for the eco-economic exploitation of the environment by the pre-Hispanic population. The studied workshops are located in the south of the Comechingones Mountains, in a sector of eroded mountain ranges with a maximum altitude of 1100 m.s.n.m. It is a very numerous type of archaeological record in this part of the mountain range; is considered the same representative of a mode of production and a long techno-economic tradition by the indigenous populations that colonized this landscape in prehispanic times.
