某水电站副厂房在服役一段时间后，空压机附近楼板出现强烈振动。为了找到合理的减振设计方案，根据该水电站副厂房现场检测结果，并通过有限元仿真反演出干扰力幅值；进而提出了一种合理的厂房加固方案，并预先计算了加固后的减振效果。将加固前后实际检测结果进行了比较，证明所提出的干扰力反演计算方法和减振方案是正确的。可为以后的工程减振实践提供有益的参考。%When the auxiliary house of a hydroelectric station was put into operation for a period, the floor plate adjacent to air compressors began to vibrate strongly. To find out the effective vibration reduction solution, the inversion calculation of disturb-ance force was conducted by FEM according to the in-situ test. Based on the analysis, a reasonable reinforced solution was pro-posed and the vibration reduction effect was forecasted. The test results before and after the reinforcement were compared, which proved that the inversion method and vibration reduction solution were correct.
