IMPROVED CALCULATION METHOD OF POINT-BERAING PILES SETTING IN FOUNDATION SOIL
A new design scheme of the point-bearing piles operation in foundation soil when calculating its setting which, unlike the calculation by SP 24.13330.2011, takes into account the friction-adhesion forces on the pile surface in contact with the top layer above the rocky soil is considered. On this basis, the calculation formula of point-bearing pile setting has been developed. By taking into account the friction-adhesion forces, the calculated setting value is more reliable compared to the existing calculation results by regulatory documents and less in value, which makes it possible to increase the operational load in setting calculations or reduce the cross section of the pile for the condition of its maximum setting and get an economic effect.
