Abstract: Based on the statistics of the failures of earth rock-fill dams, the seven key elements in operation safety assessment are listed, including dam crest structure, foundation treatment, construction material, dam deformation, stability of dam slope, seepage control, the connection of dam and foundation with other structures. The basic assessment methods include data review, on-site inspection, analysis on monitoring data, review of construction quality and design calculation, as well as the comprehensive assessment combined with operation performance and comparison with similar projects.
