Roadbed uniformity detection method, device and equipment and readable storage medium
The invention provides a roadbed uniformity detection method, device and equipment and a readable storage medium, and relates to the technical field of roadbed compaction. The roadbed uniformity detection method comprises the following steps that related parameters in the process that a vibratory roller compacts a roadbed for multiple times and reaches a standard value and compactness detection data information after each compaction are obtained, VMD is introduced into the field of roadbed compaction, acceleration signals on a vibrating wheel of the vibratory roller are processed through the VMD, a series of VMFs reflecting local characteristics of the vibration signals are obtained, VMF components representing fundamental waves and harmonic waves are confirmed, the compaction process of the roadbed serves as an energy exchange process, compaction energy generated by vibration of the vibration wheel is transmitted to the filler in a wave form, one part of energy is absorbed by the filler, the other part of energy is returned to the vibration wheel, and when the filler reaches a stable compact state, and energy exchange reaches a relatively stable state, so that the compaction degree of the roadbed is evaluated by the energy carried by the vibration signals.
本发明提供了一种路基均匀性检测方法、装置、设备及可读存储介质，涉及路基压实技术领域，包括获取振动压路机对路基进行多次压实并达到规范值的过程中的相关参数和每次压实后的压实度检测数据信息，通过将变分模态分解（VMD）引入路基压实领域，利用VMD对振动压路机振动轮上的加速度信号进行处理，得到一系列反映振动信号局部特性的变分模态函数（VMF），确认代表基波和谐波的VMF分量,并将路基的压实过程作为一个能量交换的过程，振动轮振动产生的压实能量以波的形式向填料中传播，一部分能量被填料吸收，另一部则返回给振动轮，当填料达到稳定的密实状态，能量交换达到一个相对稳定状态，以此达到振动信号所携带能量来评定路基的压实程度。
