Abstract:
This study presents the results of a critical analysis of the existing
methods of selecting the values of ground deformation modulus used in
calculating the settlement of designed foundations. The importance of
improving the reliability of the determination of the modulus of deformation
for ensuring the reliability, economic efficiency and safety of structures is
highlighted. It is revealed that the determination of the deformation modulus
is not performed at the full depth of soil samples, which can lead to the risk
of accidents at facilities. To increase the reliability of deformation modulus
determination, a method of interpolation of values based on data from
nearby wells is proposed. A new model for determining intermediate values
of the deformation modulus is presented, which can be used in calculating
the settlement of designed buildings. The results of test problems confirm
the high efficiency of the proposed method not only for the calculation of
foundation settlement using the values of ground deformation modulus, but
also for the control determination of refined values of ground deformation
modulus at the stage of geotechnical engineering surveys.
