Increasing the laying depth of the foundations fordeepened underground buildingsparts
Moscow State University of Civil Engineering, 129337, Moscow, Russia,
The article lays down the basic rules for increasing the laying depth of foundations and gives examples of how these works are carried out if the underground part of the building needs to be deepened. With the small size of the deepening of the basement in low-rise buildings, it is possible to deepen the foundations without hanging them at a lower cost. Meanwhile the risk of uneven sedimentary deformations is lower than whilehanging of load-bearing walls with the device of through beams. If it is necessary to deepen the underground part with an increase in the bearing capacity of the foundations, it is most rational to use composite piles which are submerged with pressure and are supported by existing belt foundations. The application of this method requires the mandatory installation of distributing beams under the tape foundation, providing the transfer of the load from the pile indentation on the volume of the structures, significantly exceeding by the weight of the indentation force.
