Аннотация

The paper presents a numerical and analytical method for determining the modulus of elasticity of the soil, based on experimental results on the natural frequencies of vibration of a pile embedded in a soil mass and their theoretical dependence on the modulus of elasticity of the soil. Experimental results on the dynamic behavior of a pile embedded in a soil mass and numerical results based on the finite element method, which provide the construction of the dependence of the natural frequencies of vibration of the pile on the modulus of elasticity of the soil, are given. As a demonstration of the reliability and efficiency of the method under consideration, a comparison of numerical results on the natural frequencies of vibrations of the pile with different weights at its free end at the found dependence of the modulus of elasticity of the soil and the corresponding experimental results is given.
