ROCK-FILLED DAM AND METHOD OF ITS CONSTRUCTION

摘要

Usage: to the field of hydraulic engineering, in particular to constructs rockfill dams and methods for their construction in conditions existing reservoirs. The essence of the invention: in the dam body 1 consisting of riprap transition zone 2, a composite core formed, the upper part 3 which contains the fine fraction of the rock mass, and the lower part 4 is made of okomgo ehy Lect. roH u and d 3 iuki stteiz th mkovannogo clay soil, adjusted to limit state density, and has a height defined by the ratio of 5 K et al (0,08-0.13) NSCR where NSCR - the pressure in the well when exposed to the carburizing curtain in a cracked bedrock; Ks - a safety factor. With the construction of the dam first otsypaets in water on a base layer omono- lichenie sloping clayey soils compacted to blocks 10 limiting state density. Then manufac t pioneering manner with ridge backfilling the embankment fines rock mass on the layer of clay as long as the base layer of the fine fraction of the rock mass on the layer of clay as long as the base layer of the fine fraction of the rock mass height lower glycerol. oily layer 5 reaches the like. Further again with ridge mound manufac t dumping pioneering manner by following the slope of the rock mass layer omonolichen- GOVERNMENTAL sloping clayey soils, and the process is repeated. Thus at the boundary interface of the lower and upper layers of the composite core formed comb. 2 s.p.f-ly. 2 yl. AA (LS About 00 ke of 00 iO
