... thicker diaphragm walls, temporary support elimination, no need of ground water level lowering and reduction of the bottom slab thickness. In this alternative diaphragm walls constituted the retaining wall, while the columns of jet-grouting were disposed as to form the support. INTRODUCTION To provide...

... hillside slope, the Juniata River flood plain is generally covered with recent alluvium followed by bouldery granular materials. The alluvium contains surficial deposits of relatively soft silty clay and sandy silt. The hillsides are relatively free draining; and the natural ground water level in the steep...

... or jointed rock is often encountel:d in practical cases. BEN have been applied in modelling the hydraulic splitting of stratified or jointed rock with which we draw the tunnel layout curves under different water levels in stratified or jointed rock for two slopes. Our conclusions are that the steeper...

... top water level at 1158 metres above sea level. NorddØla is diverted to Rundavatn, the other intake basin. Rundavatn is dammed up to 1040 metres above sea level by a rockfill dam. The two Lang-Sima generating sets can run alternately on water from Langavatn or Rundavatn. From the intakes, the water...

.... Construction of the dam began in 1971 and it was completed in 1979, meanwhile nearly 150,000 meters of borehole was drilled for the grouting. The reservoir began to be filled in November 1979 and reached its high water level in November 1980. The measurements of the deformation of the dam and the leakage...
