Dynamic centrifuge model tests on asphalt-concrete core dams
Géotechnique, 2009In this research, the dynamic behaviour of a rockfill dam with an asphalt-concrete core has been studied utilising centrifuge modelling. Instruments including accelerometers and LVDTs were installed within and on the models and response accelerations and induced deformations were recorded.

Causes of the abnormal seepage field in a dam with asphaltic concrete core
Journal of Earth Science, 2016Asphaltic concrete core (ACC) dams are widely built in China. Many ACC dams perform well, but others have experienced significant leakage including the case in western China studied herein. A numerical model of saturated-unsaturated water flow was adapted to simulate the seepage through the dam. By comparing the normal and abnormal seepage fields under

Construction of compacted asphaltic concrete core walls of earth dams
Hydrotechnical Construction, 19901. Compacted asphaltic concrete has become widespread abroad as a material for core walls of earth dams. Construction of a compacted asphaltic concrete core wall is accomplished by means of self-propelled asphaltic concrete placers. Our country presently does not have such equipment. 2.

Strength parameters of asphalt concrete used in core zone of earth dams
2009Strength parameters of asphalt concrete used in earth fill dams' core were studied by conducting cyclic and monotonic triaxial tests on asphalt concrete samples. Results obtained from more than 120 cyclic tests showed that asphalt concrete behaves properly under cyclic loading and specimens stay intact after applying 5000 cycles.

Experimental study of asphaltic concrete dynamic properties as an impervious core in embankment dams
Construction and Building Materials, 2013Abstract The seismic behaviour of asphaltic concrete used as an impervious core in embankment dams was investigated. To evaluate the specimen’s dynamic behaviour, an extensive series of monotonic and cyclic triaxial tests were carried out. Bitumen content between 5.5% and 7.0% with 0.5% increments were selected for the tests.

Whether hydrofracture failure is likely to occur in an asphalt concrete core rock-fill dam or not is one of hotspot problems widely concerned by the engineering community. In this paper, the authors adopt effective stress method to analyze the stress deformation in the core wall of Maopingxi dam and evaluate the hydrofracture problem in dam&s core wall
