Abstract

The construction of pile foundations in permafrost conditions is a durable and cost-effective design that shows high performance of piles in contrast to slab, block and strip foundations. In the Russian experience of construction in permafrost conditions, the most common methods of piling are the following: sinking method, driven method, drill-and-pile method, and drill-and-pile method. Descending method, where the piles are driven into thawed and liquefied soil. Pile driving method, in which piles are driven into frozen ground using percussion mechanisms. Drill-and-pile method, which combines the use of sinking and drilling piles. Drill-and-pile method, in which a borehole is drilled first and then the piles are driven into the frozen ground. Organisational and technological flow reliability involves the efficient use of resources, compliance with standards, organisation of work processes and safety. This allows the objectives to be achieved efficiently and ensures reliable process operation. The main indicators are: system uptime without failure T_O, delays in information transfer H_O, equipment reliability P_O, material quality F_O, operator errors D_O. In fact, the control of these indicators affects the organisational and technological reliability of the flow and the work production system as a whole.
