摘　　要：在二级坝泵站主厂房屋面、主厂房高程29.77m处的楼面布设了15个DH610传感器,根据随机振动理论中的地脉动测试方法测试了主厂房的自振频率及其结构的加速度、速度、位移时程。实测结果表明,各种工况下主厂房结构的最大加速度、最大速度、最大位移均在现行泵站设计规范规定范围之内。Fifteen DH610 sensors are placed on the roof and 29.77 m height floor of secondary dam main powerhouse of pump station. Based on random vibration theory, the natural frequency of vibration, acceleration, velocity and dis- placement of main powerhouse are detected based on the microtremor test method. The measured results show that the maximum values of acceleration, velocity and displacement of main powerhouse structure are within the allowable scope of the existing design specification of num~ station.
