基于Matlab软件应用的沥青路面波形重组研究

Research on Asphalt Pavement Waveform Reorganization Based on Matlab Software Application

沥青路面的波形是路面起伏程度的主要反映,通过单一的正弦或余弦函数来表示路面波形,不能够完整地体现路面真实情况及分析平整度与波形参数之间的关系。同一条道路在不同路段上会呈现出多种路面波形,车辆行驶过程中产生的动荷载以及乘客舒适性体验也会大有不同,因此可以考虑采用多个正弦函数表达式来模拟路面波形。文章以湖南省某试验段为例,对其进行平整度检测,经数据处理后,根据整条道路路面的波形函数公式,运用Matlab软件绘制各区间的路面波形,为保证路面舒适性提供合理的施工控制参考指标。

The waveform of asphalt pavement is the main reflection of road surface undulation,a single sine or cosine function can be used to represent the road surface waveform,but it can not fully reflect the actual situation of road surface and analyze the relationship between the flatness and waveform parameters.The same road will show various road waveforms on different road sections,and the dynamic load and passenger comfort experience generated during vehicle driving will be also very different.Therefore,multiple sine function expressions can be considered to simulate the road surface waveform.With a test section in Hunan Province as the example,this article conducted its flatness detection,then,after data processing,and according to the waveform function formula of entire road surface,this article used the Matlab software to draw the road waveforms in each section,so as to provide a reasonable construction control reference index for ensuring the comfort of road surface.
