Method for Determining Resumption of Train Service on Railway Embankment Damaged by Rainfall

Abstract

Since the stability of railway embankments damaged by rainfall is not easy to assess, the need for temporary restoration is often determined on the strength of experience of inspectors, or the damaged embankment is restored to its original shape. As a result, there are cases where temporary restorations are carried out with specifications which exceed what is required for embankments that already meet performance requirements for train operation. This study proposes a method for evaluating the performance of damaged embankments or temporary restoration embankments in terms of stability and settlement during train operation, and to quickly determine whether train operations can be resumed on a damaged embankment.
