声振法检测室外水泥混凝土路面脱空试验
|
摘要
目的为了及时处理水泥混凝土路面板脱空,准确和快速地判断脱空位置.方法笔者借助拾振器和计算机采集系统,通过对大连市区内的水泥混凝土路面进行现场试验,记录并分析水泥混凝土路面脱空与非脱空区域的加速度特性、振动时间和频谱特征,探索水泥混凝土路面脱空与非脱空区域的机械波的振动规律.结果脱空区域路面板最大振幅对应的卓越频率在100～130 Hz,非脱空区域路面板最大振幅对应的卓越频率在200～260 Hz.结论水泥混凝土路面板的脱空性与其振动信号参数有密切的相关性.脱空水泥混凝土路面板比非脱空水泥混凝土路面板的加速度大,振动时间长,主频高.
In order to deal with the void of cement concrete road slab,quickly and accurately judge the position of the void. In this paper,the vibration pickup and computer acquisition system were used by the author,through carrying out the field experiment of cement concrete pavement in Dalian,the acceleration characteristic,vibration times and frequency spectrum characteristic of the cement concrete pavement void and no void were recorded and analyzed,the vibration lawof mechanical wave of cement concrete pavement void and no void were explored. The results showthat the void property of cement concrete pavement and its vibration signal parameters have closely relationship. The acceleration of void cement concrete pavement is larger,the vibration time is longer,the frequency is higher than that of no void cement concrete pavement.
