Embodiment 1
[0054] This embodiment provides a roadbed compaction evaluation method.
[0055] see figure 1 , the figure shows that the method includes step S100, step S200, step S300 and step S400.
[0056] S100. Obtain the time-history curve of the vertical acceleration signal of the vibrating wheel. The time-history curve of the acceleration signal is collected by an acceleration sensor arranged on the vibrating wheel of the road roller. ;
[0057] S200. Divide the acceleration signal time-history curve into a plurality of sub-curves;
[0058] Specifically, this step is to divide the acceleration signal time-history curve collected during a subgrade compaction process into several sub-curves, so as to be conveniently brought into the subsequent evaluation index algorithm for calculation.
[0059] Specifically, this step includes step S210 and step S220.
[0060] S210. Obtain the length of the detection unit for roadbed compaction and the total length of the compacted roadbed;
