WATER-CONDUIT STRUCTURE UNDER ROAD EMBANKMENT ON DEFORMABLE BASE

摘要

The water-conduit structure under road embankment on deformable base is provided with flexible closed non-stretched tubular shells placed along the arch of vault in the middle in width of the embankment part at the outer surface, and those shells are filled with air at pressure p that is determined through the formula: , where is k - coefficient equal to 0,7 0,9; qâ - vertical soil pressure on vau - coefficient of side pressure equal to the ratio of the side pressure of soil on vault qá to the vertical one qâ.
