砾石骨料破碎率对沥青混凝土心墙坝应力应变影响分析
Analysis on the Influence of Gravel Aggregate Crushing Rate on Stress and Strain of Asphalt Concrete Core Wall Dam
摘要
Abstract
Through indoor static tri-axial test to obtain Duncan-Zhang E-μ model parameters,an asphalt concrete core wall dam in Xinjiang is calculate by using ABAQUS finite element software.The stress and strain characteristics of dam body and core wall during the period of completion and full storage are analyzed under the conditions of different gravel aggregate crushing rates.The results show that the stress and strain characteristics of dam body are little affected by the crushing rate of coarse aggregate in asphalt concrete core wall,and only the major principal stress in core wall will increase with the increase of coarse aggregate crushing rate,but all stresses and strains in core wall are in safe range.Therefore,the natural gravel aggregate can be completely used in asphalt concrete core wall dam.关键词
