| Summary: | The OA-11 dam on the Eastmain River in the James Bay Region of northern Quebec was designed without conventional cofferdams. The river section of the dam was constructed by end-dumping and dozer pushing of granular fill and achieving closure and diversion of the river through a spillway located in a rock abutment on the south bank.The fill was then compacted by using the vibroflotation method. The fill thickness varied from 4.5 to 15 m, the compacted area being 68 000 m 2 while the volume was about 725 000 m 3 .This paper gives the properties of the fill, the equipment used for compaction, the control method used to assure compliance with specifications, and the results of the compaction programme. Keywords: dam construction, compaction, density, vibroflotation, equipment. |
