SPATIAL BEHAVIOR OF A BORED PILE DIAPHRAGM ON A ROCKFILL DAM BODY
The article considers the results of numerical modeling of stress-strain state of 69 m high rockfill dam with 145 m crest length, where a seepage-control element is presented by a diaphragm of clay-cement concrete bored piles. It is shown that in spatial conditions the strength state of clay-cement concrete improves, that there is no danger of opening the vertical joints between piles, however, the strength of the contact between the diaphragm and rock may decrease.
