摘　　要：采用三维有限元法模拟闸墩的主要工况和蓄水过程,研究在各种可能工况下闸墩顶部竖向与水平位移的变化规律,获得坝顶竖向与水平位移变化范围;结合枢纽本身特性、库区温度条件和现有观测资料,获得温变及时变产生的位移变化范围,进而给出闸墩位移的监控指标限值,为大坝监测提供定量依据。The changes of vertical and horizontal displacements on the top of pier in a large navigation-hydro complex under different operation conditions and water-storage process are studied by using three dimensional finite element method, and then the vertical and horizontal displacement ranges of crest are obtained. At the same time, the displacement component changes caused by temperature change and time varying are also gained according to structure characteristics, reservoir area temperature and existing monitoring data. The limits of pier displacement monitoring components are finally proposed to provide a quantitative basis for the monitoring of dam.
