混凝土大坝的耐久性与服役寿命评估将成为21世纪我国坝工界的重大理论和技术课题.重点规划了以整体稳定性为基准的混凝土坝服役寿命仿真分析理论体系,并对混凝土材料与岩体的结构衰变、控制性结构面疲劳损伤、关键防渗体系衰变、关键加固体系衰变、大坝-坝基多物理力学场的空间分布规律、大坝-坝基多物理力学场的时间演进、寿命终止(或退役)的监控预警指标等问题的研究现状进行了总结评述.最后提出了建立混凝土坝服役寿命仿真分析理论体系的若干关键科学问题.
The evaluation of the durability and service life of concrete dams will become a major theoretical and technical issue in the field of dam industry in China in the 21st century. The theoretical framework of the service life simulation analysis of concrete dams based on the overall stability is mainly planned. Concrete materials and rock Body structure decay, fatigue damage of control structural plane, decay of key impervious system, decay of key reinforcement system, spatial distribution of dam-dam multi-physics mechanics field, time evolution of dam-dam multi-physics mechanics field, end of life (Or retired) monitoring and early warning indicators of the status quo of the study were summarized.Finally, some key scientific issues to establish the theory of service life simulation of concrete dams were proposed.
