Abstract
In current years the use of asphaltic concrete core dams are increased especially in some areas with shortage of clayey materials. These dams also have less earth work in comparison with clay core dams. Despite of many advantages of this kind of dam in compression of other types, the behavior of these dams against earthquakes and seismic condition isn't clearly specified. In this research using CA2 program (Finite difference Code) Some numerical studies about the behavior of asphaltic concrete core dams with various height and slopes to understand the influence of dam geometry on behavior of these dams under earthquake condition were done. Application of dams with asphalt concrete core is a relatively novel method especially in Iran. Iran is among regions with high seismicity risk. Therefore, investigation and studying the behavior of such types of dams in earthquake conditions is of more importance considering the novelty of implementing asphaltic core dams. In this research, behavior of asphaltic core dams have been studied under earthquake loading using nonlinear dynamic analysis method and a method is presented for assessment of seismic stability of these types of dams in earthquake conditions based on nonlinear dynamic analysis. Results of the proposed method in this research beside other existing methods can assist designers of asphaltic core dams in judgment about dam stability during earthquake occurrence.
