Inversion and Analysis of Working Behavior of Super-High Arch Dam Based on Field Monitoring Data

In this paper, the dam of Baihetan Hydropower Station was taken as an example to establish a refined three-dimensional finite element model (FEM) dam-dam foundation based on comprehensive analysis safety monitoring data during whole life cycle and simulation for process dam, so accurately understand working behavior impounding process, do feedback influence mechanism overall deformation arch in construction, impoundment operation, predict evaluate potential risks different water levels thus providing scientific basis regulation decision-making.
