Os modelos de partículas têm vindo a ser utilizados no estudo do comportamento de materiais quase-frágeis, em particular do betão. Este tipo de modelos permite a consideração da distribuição, quantidade e forma dos agregados ...

To understand the performance of the dam during the first filling, it is crucial to predict in real time the displacement and the stresses due to the water reservoir level and environmental conditions. Particular attention ...

Monitoring is a key activity to ensure the structural safety of dams and is used for detection of deterioration, including local degradation issues and more extensive deterioration scenarios, such as the development of ...

The current document compiles some of the most relevant information concerning the symptoms and respective causes of common anomalies observed in concrete dam bodies. These include physical degradation phenomena, like ...

The Ribeiradio-Ermida multipurpose hydro scheme, built between July 2010 and the end of 2015, is the first major project in the Vouga River basin and is located in the centre of Portugal. Its main purposes are power ...

Descreve-se a atividade de investigação realizada no projeto DamConcrete até 2017, no âmbito do comportamento reológico do betão de barragens considerando trabalho experimental (laboratorial e in situ), modelos analíticos ...

A fully coupled hydromechanical analysis of the water flow through the rock mass discontinuities of three hypothetical gravity dams of different height was carried out. It was assumed that the dams had similar rock mass ...

The rock type plays a key role in the way in which the outermost layer of the cement interacts with the formation, in wells under geothermal environments. The penetration of cement into the rock is controlled by the porosity ...

O presente relatório descreve de forma sucinta a atividade desenvolvida no âmbito do projeto DAMFA - Soluções de ponta para a avaliação sustentável das fundações de barragens de betão, até ao final de 2017.

The mechanical property characterization of dam concrete is a challenging task mainly due to the use of large aggregate sizes. The properties of dam concrete are often evaluated from wet-screened concrete tests using ...
