| Title of the article | Study of vibrocreep of sandy soils under low-frequency vibration effects in the device of dynamic triaxial compression |
| Abstract. | Problem statement. The bases of structures of urban development are almost constantly exposed to dynamic loading from various sources. Long-term dynamic loading leads to the development of vibrocreep deformations or liquefaction of water-saturated sandy soils. As a result, there is a risk of base failure. The purpose of the work is to study the behavior of sandy soils under the influence of a low-frequency vibration load. The tasks of the study are to carry out the analytical review of the literature of the studied topic and experimental confirmation of the hypothesis about the dependence of the unit strain value on the number of cycles and the frequency of dynamic loading. Laboratory tests were performed on a device of dynamic triaxial compression under conditions of closed drainage. The results of the study are presented in the form of graphs of the dependence of axial deformations on the time of action of the dynamic load and the number of cycles. In the course of the research, a significant decrease in the modulus of deformation in the process of vibration was recorded. Conclusions. The results obtained in the course of the study can be useful in the design and selection of technologies for the production of zero cycle construction works |
