Assessment of the Operational Reliability of Railway Water Pipelines in Seismically Active Areas

Abstract

In this study, the stress-strain state of the railway subgrade and the water pipeline system under seismic and operational loads was assessed based on digital modeling. Calculations were performed using the finite element method based on a three-dimensional model. The research results revealed that soil moisture, embankment height, and pipe wall thickness significantly affect the deformation and reliability of the structure. An increase in soil moisture leads to a decrease in the deformation modulus and an increase in the amount of settlement. Decreasing the pipe wall thickness reduces the rigidity of the structure and does not ensure seismic safety. It has been substantiated that digital modeling methods are an effective tool for assessing the stability of railway infrastructure and developing optimal engineering solutions.
