Abstract
Based on the commercial software ABAQUS,the Duncan-Chang E-B model is realized by using its subroutine interface.The three-dimensional nonlinear finite element analysis of a 100-meter asphalt concrete core wall dam is carried out to simulate the working characteristics of the dam under different working conditions.The calculation results show that the vertical displacement of the dam body during the completion period and the impoundment period is 65.88 cm and 67.95 cm,both within 1％,and the stress distribution is reasonable.Under the action of water pressure during the impoundment period,the stress and deformation of the dam body and the core wall are increased compared with the completion period.The calculation results can provide reference for similar projects.关键词
