Estudio de las propiedades geotécnicas de los sedimentos acumulados en el embalse de la presa de Proserpina (Mérida, España)

Abstract

This work study the geotechnical and mineralogical characteristics of the sediments acumulated since the Romans epoch in the Porserpina dam (200 A.C.) sited in Merida (Badajoz, Spain). From the geological point of view it's a very recent deposit, aging less than 2000 years; very soft and saturated, with silty-clay granurality and coming from the sourronding granitic rocks degradation. Multiple field and laboratory geotecnic tests are conducted over unaltered samples from whitch identification, state, strength and deformability properties are obtained using technics for soft soils characterization like seismics tests, geophysic testification tests or piezocone and vane tests
