<b>A Simple Method for Predicting Track Settlement Caused by Culvert Pipe Damage</b>
In this study, we developed a nomogram to easily predict track settlement due to culvert pipe damage. First, a calculation method was developed to estimate the reduction ratio of the subgrade reaction coefficient under railway tracks. The accuracy of this method was verified by comparison with trap-door tests and field tests. Secondly, to produce the nomogram, we calculated track displacement under conditions of reduced subgrade reaction.
