During the later period of construction of Tianshengqiao con crete faced rockfill dam(CFRD), cracks appeared in the upstream fill sl ope. The main reason was the nonuniform deformation. The treatment methods were: for cracks with opening less than 1 cm, the cracked slope was compacted with added effort to eliminate cracks; for cracks with open ing greater than 1 cm , crack grouting was carried out . The practice demonstrated the treatment was successful. Careful analysis of the rel ation between sectionalized filling and crack emergence is of significa nce in guiding the construction design and drawing out filling plan fo r a high CFRD.
