LATERAL BALLAST RESISTANCE AND STABILITY OF TRACK IN EARTHQUAKE

The behavior of the railway track in earthquake was studied through experiment and theoretical analysis. The experiment was performed with real tracks in the RC-box placed on the vibrational table of 5 times 5 sq m in dimensions. The conclusions are as follows: against the earthquake acceleration with which railway structures are designed, 83% of the static lateral ballast resistance of track is maintained in the track on the Shin Kansen and 78% in the track with PC-ties and crushed stone ballast on the narrow gauge lines. The long weld rail track holds the safety factor at least 1.15 for the buckling due to temperature rise in the earthquake with the same acceleration mentioned above.
