Abstract
Most of the reservoir dams in China are made of earth and rock. There is no mature and perfect control calculation theory for infinite deep pervious foundation in the existing dam foundation seepage control theory. The research on seepage control of infinite permeable foundation or thick covering layer foundation, has a great theoretical and practical significance in building dam on these foundation. In this paper,a mathematical model of dam foundation seepage flow was established under more ideal conditions,the dam foundation seepage for infinite deep pervious foundation was simulated by the finite difference theory and software Visual MODFLOW.and seepage control effect was analyzed in different vertical seepage control programs. The calculation method is both discreet in theory and feasible in practice, which fully demonstrated the water-proof effect of impervious curtain, and provides a useful reference for the dam foundation seepage numerical simulation.关键词
