摘要:
针对混凝土坝长期服役过程中结构变形性态的时变问题,在对混凝土坝变形时变效应成因分析以及中国特高混凝土坝运行特点总结的基础上,研究了特高混凝土坝高应力及高水压力对变形时变效应的影响,以及坝高对特高混凝土拱坝变形时变效应监控分析的影响。分析结果表明,在从筑坝材料固有性能及服役期材料性能演变的角度研究混凝土坝变形时变效应时,需建立适合特高混凝土坝运行特点的流变本构模型和环境损伤模型,且特高混凝土坝变形监控分析需要考虑坝体空间整体性的时变。
Abstract:
Aiming at the time-varying problem of deformation behavior of concrete dams during their long-term operation, cause analysis of deformation time-varying effect of concrete dams and the exploration of operation characteristics of super high concrete dams in China were conducted firstly in this paper. Then, the influences of high dam stress, high water pressure and dam height on the deformation time-varying effect of super high concrete dams were studied. Analysis results show that the rheological constitutive model and environmental damage model need to be established in accordance with the operation characteristics of super high concrete dams when studying their deformation time-varying effect from the views of dam material inherent property and its evolution during operation, and the time-varying of deformation spatial integrity should be considered in the safety monitoring of super high concrete dams.
