摘要
Abstract
In order to master the dynamic characteristic index of asphalt concrete core wall,the dynamic characteris-tics of asphalt concrete core wall were taken as the research object.The dynamic triaxle test of asphalt concrete under the condition of setting temperature,consolidation ratio and confining pressure was carried out.The maximum dynamic modulus,damping ratio and modulus coefficient of asphalt concrete were sorted out by equivalent linear model,and the variation law and influencing factors of each index were analyzed.The test results show that the maxi-mum dynamic modulus increases with the increase of confining pressure and consolidation ratio,the damping ratio decreases with the increase of confining pressure and consolidation ratio,the modulus coefficient K increases with the increase of consolidation ratio,and the exponent n decreases with the increase of consolidation ratio.In addition,the normalized empirical formulas of Gd/Gdmax and γd/γr were established,which can provide reference for the application of similar projects.关键词
