Based on the vibration of circulating water pump in a coal-firing power plant phase II in Indonesia, analysis had been carried out from different aspects for the problem. The key factors concluded were insufficient taper plates and unqualified secondary grouting. Meanwhile, single foundation, high structure above the foundation, higher speed than normal and insufficient structural stiffness were formed the influence factors, which led to the undesirable disposal results. The vibration of 3B was still exceeding 4.5mm/s specified by the standard, 3A was just meeting the value, and the vibration of 4A, 4B was 2.8mm/s. The advice and suggestion had been summarized.
