A single-track railway bridge had obvious quality disfigurements through inspection. The causes that lead to it were analyzed. The method of rehabilitation and strengthening of the pier was stated. The bored piles were constructed around original base slab, new base slab set up at the piles' top was firmly connected to original pier shaft.
