| 摘 要： | 针对水泥混凝土路面板底脱空,利用加速度传感器采集处于不同状态(板角脱空、板角非脱空)和不同厚度的混凝土板数据,通过频谱分析得出:厚度为20 cm、18cm的脱空混凝土板,试验点布置在板角区域时,最大振幅对应的频率为200～400 Hz,试验点布置在非脱空区域时,最大振幅对应的频率在500～700Hz;厚度为20 cm、...

| Abstract: | For the defect of concrete pavement plate being empty,the use of acceleration sensor collecting data in various states(plate angle separation,plate angle of non-void) and different thickness of the concrete slabs.through analyzed by spectral analysis,it shows that a thickness of 20 cm,18 cm's Void concrete slab,the maximum amplitude of the corresponding frequency is from 200 Hz to 400 Hz,when the testing points are arranged in the region of the corner of concrete slabs.On the contrary,testing point arrangem... |
