1-5 EFFICIENCY OF OVAL SUPPORT WALLS IN ENSURING THE SEISMIC STABILITY OF RAILWAY STRUCTURES

Abstract

This article investigates issues of increasing the stability of railway embankments in seismically active regions. The disadvantages of traditional rectangular retaining walls are analyzed, and the use of innovative oval-shaped structures is proposed instead. Based on the results of digital modeling conducted in the Midas GTS NX software package, the stress-strain state of the oval walls was assessed. The results showed that the oval shape effectively distributes soil pressure due to the "arc effect."

Keywords: railway embankment, seismic stability, oval retaining wall, Midas GTS NX, arch effect, earthquake.

Introduction. Today, the modernization of transport infrastructure in the Republic of Uzbekistan is considered one of the priority areas of state policy. In particular, the Decree of the President of the Republic of Uzbekistan No. PP-329 dated October 10, 2023, "On measures for the radical reform of the railway transport sector," as well as other regulatory documents related to the sector, emphasize ensuring transport safety and the implementation of digital technologies (BIM, AI).
