Abstract Superhigh arch dams generally locate in complicated foundation. The failure，reinforcement and stability mechanism of foundation are facing with challenging original problems，such as：mechanical parameter and strength reasonable selection of jointed rocks；cracking problem in the heel and toe of dams；reinforcement measures for atypical faults and altered rock；grouting timing design for toe area of dam；anchorage force damage and nonlinear evaluation for integrity stability. In this paper，these key problems involved in the research methods，and reinforcing measures to carry on the discussion and analysis based on practical engineering. The micro-macro transfer method is proposed for coupling nonlinear analysis method. By employing this method，numerical simulation and experimental investigation on foundation failure，reinforcement and stability evaluation of superhigh arch dam need to further carry out for servicing dam design and construction.
