Emphasis is placed on effects of cross valley differential settlements, and the end of construction core load-settlement behavior, particularly in vicinity of abutments. The effects of core material type (mixed clayey sand material versus pure clay), on stress-strain behavior are examined. As a case study the Masjed Soleyman clay core is analyzed considering different types of materials, and a range of core material deformation properties. A 70% reduction in depth of tensile zones near the core- abutment interface was achieved by inclusion of contact clay material at the core bottom. Comparison of analysis results and instrumentation data suggested a good agreement between results.
