Seismic Analysis of the Garmrood Embankment Dam with Asphaltic Concrete Core
Soils and Foundations, 2009 ABSTRACT The seismic behaviour of asphaltic concrete core dam under earthquake loads has been studied. The study consists of three parts; element tests on asphalt concrete, numerical analysis and some model tests. In the first part, a series of triaxial monotonic and cyclic tests were performed at the Norwegian Geotechnical Institute (NGI)'s ...

Dynamic Centrifuge Modelling Tests for Asphalt Concrete Core Dam
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Dynamic centrifuge modelling tests are carried out to study the seismic behaviour of a sand-gravel dam with asphalt concrete core wall. The acceleration response, deformation, core wall stress and stability are analysed under design and check seismic intensity. The crest acceleration amplification factor is 2.7~3.0.
