BORED PILES WITH THE BROADENING IN THE CONTEXT OF A LARGE DEPTH OF FREEZING

Abstract

In the climatic conditions of Siberia pile foundations are working under the influence of forces of frost heave. Therefore, the length of piles accepted to take into account anchoring. However, in the construction of light buildings, bearing capacity of foundations used for no more than 30 to 40 % and most of the funds being spent inefficiently. In this work we consider the design of piles, resulting in lower costs for construction in these conditions is bored piles with the widening. From calculations it is seen that a variant of the bored piles with the broadening in comparison with the conventional reduces the volume of concrete production piles (and therefore cost) 44% (almost 2 times).
