+ Abstract

For the safe operation of any structures, it is necessary at the survey stage to correctly assess the physical and mechanical properties of the soils. The deformation modulus is used in the design of any construction facilities and is one of the main design parameters of soils. At the same time, the modulus of deformation of the same soil determined in different ways, depending on the method of determination, may differ several times. The article analyzes the reasons for such a large discrepancy in the values of the deformation modulus of one soil. At the beginning, the error of interpolation and measurements is estimated; various methods for determining the modulus of deformation are considered. It is concluded that the results of compression, stamp and triaxial tests are incomparable in principle, since they are carried out under different boundary conditions. When using methods for determining the modulus of deformation with different boundary conditions, physically and mathematically justified transition coefficients should be used to bring the results to a single denominator. However, the authors believe that the main problem is that for natural soils, this characteristic is a nonlinear function of three independent arguments – normal stress, internal pressure of the soil and the area of external influence of normal stress on the soil. In this regard, the value of the module estimated by some abstract number, which is not tied to the normal voltage, is recognized as physically and mathematically illegal.
