As the first executing institution, NHRI, in cooperation with other 7 units, has completed the key research on safe construction of high concrete faced dams, putting forward a new concept for deformation adjustment design, and establishing a deformation adjustment criterion and computation methods for deformation safety design. Computation and geotechnical testing were conducted to reveal the interaction among dam body, foundation, seepage system and high retaining walls to develop novel dam construction technology under complicated topographical and geological conditions. New monitoring facilities and deformation computing models were developed to form a complete set of dam safety monitoring technology for high concrete faced dams. The research findings were applied to over 25 engineering projects with considerable economic benefits.
