To improve the transport infrastructure of the Republic of Uzbekistan, the monolithic structure of bridges and overpasses began to be used. The article presents the calculation of a monolithic overpass on the 1083rd km of the M-39 highway passing through Samarkand. The results of the calculation of a monolithic overpass from dynamic load are presented based on the records of two real seismograms for two dangerous earthquakes for the system with spectral composition: Gazli (Uzbekistan) and Manjil (Iran). The calculations show that to ensure guaranteed seismic safety of transport structures, it is necessary to carry out design calculations based on sets of records of earthquakes that occurred, close in dominant frequencies to the characteristics of the construction site. Such a provision should be introduced into the relevant regulatory documents.

The article deals with the seismodynamics of underground pipelines of various configurations under spatial seismic influences. The stress-strain state of spatially located underground pipelines of complex orthogonal configuration at different angles of seismic load incidence was determined. Several problems were solved by analyzing numerical results of the seismodynamics of underground pipelines of complex orthogonal and non-orthogonal configurations.

“…To date, in domestic and foreign science, there are theoretical and experimental studies for determining the stress-strain state [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and stability [17][18][19][20][21][22][23][24] of underground pipelines interacting with the surrounding soil under seismic effects. A theory of propagating seismic waves in an underground pipeline and surrounding soil called the wave theory of seismic resistance of underground pipelines is proposed in [12].…”

Studies on the effect of changing the stiffness coefficient along the length of the pipeline on its resonant vibration mode are considered in the paper. A computational model of transverse vibrations of the pipeline located in soil with different properties is created. Theoretical and computational studies to solve the problems of stability of underground pipelines located in the soils with different properties under seismic effects are carried out. It is revealed that the vibratory process of the pipeline can be realized at frequencies close to resonance. The results of the study are presented as curves of distribution of displacements of pipeline sections along the length at dimensionless frequencies. When the pipeline vibrates with a frequency close to the resonant frequency, the displacements of pipeline sections can take very large values. It is shown that at frequencies close to resonance, the values of moments can be large in the pipeline sections, which are the reasons for the loss of pipeline stability.
