Simplified method for core dam saturation line calculation
摘要
Abstract
The saturation line position is one of the main bases for flow characteristics evaluation of earth rock dams, which must be calculated before the comparing and selecting the appropriate anti-seepage reinforcement program of dangerous earth-rock dam. Considering the relationship betw een the relative permeability coefficient of the dam and the cut-off wall, asimplified cal-culation met hod was proposed to estimate the saturat ion line of the core dam by theoret ical analysis and numerical calculation. Afitting formulation was developed to calculate the position of the saturat ion lines. The simplified calculat ion methods proved to be reasonable w hen com paring with the results of finite element methods based on the dam of Baiyashan Reservoir. The simpli-fied calculation method can significantly reduce the computational workload w hen comparing and selecting the reinforcement program of small and medium-sized reservoir dams.关键词
