Stress and Deformation Characteristics of Asphalt Concrete Core Dam on Deep Overburden Layers

Abstract:

Taking the FEA of a 100m high asphalt concrete core dam on 120m deep overburden layers as an example, this paper discusses the stress and deformation characteristics of the high asphalt concrete core dam on thick moraine cover foundation, to provide reference for other similar projects. The calculation results show that there is obviously core arching effect in earth-rock dams with asphalt concrete core, and this effect will be weaken after water impoundment; the asphalt concrete core can adapt the deformation of the foundation freely. This paper also discusses the stress and deformation of the core of asphalt concrete core dam when water level fluctuation.
