Simulation on Thermal Stress and Damage of Gaixiaba Dam during Construction Period
摘要
Abstract
According to the actual pouring of Gaixiaba Arch Dam, the three-dimensional thermal and stress fields of dam during whole construction period are simulated by using ANSYS and its secondary developed programs, and the maximum temperature and thermal stress are obtained. At the same time, the damage status of dam is also simulated by self-developed damage finite element program, and the damage fields of dam in some key construction moments are achieved. The simulations show that the thermal stress of dam is much less than the design allowable value and the damage value is smaller after implementing reasonable temperature control measures, and the dam will not appear macro crack during construction period.关键词
