FIELD: construction.SUBSTANCE: invention relates to construction and can be used for determination of bearing capacity of piles in existing foundation at examination of buildings before reconstruction. Method of piles testing by static load includes digging of foundation, exposure of grid sole, separation of pile from grid, pile static test by pressing-in, tested pile displacements measurement. Before separating pile from grid on tested and adjacent piles extensometers are installed. During test change in stress condition of piles shaft is recorded. Then value of effect of adjacent piles on tested one is evaluated.EFFECT: technical result consists in improvement of reliability and accuracy of determining bearing capacity of piles in foundations of buildings by static load.1 cl, 3 dwg |
