摘要
FIELD: construction. SUBSTANCE: method for control of load-carrying capacity of driven piles includes determination of coefficient depending on pipe material, pile point ground supporting area, mass of diesel-hammer, mass of driven pile and pipe cap, coefficient of impact recovery, hammer impact energy, operation coefficient depending on adopted technology of pile driving, depth of pile sinking from ground surface near pile, perimeter of cross-section of pile stem, friction force of pile surface with ground, number of hammer impacts on pile, side pressure of ground acting at the level of pile point, and coefficient considering value of decrease of pile friction with ground during its driving. Pile load-carrying capacity is calculated by empirical formula. EFFECT: higher efficiency.
