摘　　要：介绍目前国内外几种具有代表性的压实物料密实度在线评价方法。指出现有密实度在线评价方法大多数只考虑压路机系统垂直方向的振动特性,而忽视压实系统在水平方向的耦合振动特性问题。提出采用压实系统垂直方向和水平方向多个振动特征参数建模在线评价压实物料密实度的一种新方法,该方法可以消除因任何因素引起的压实系统耦合振动影响,特别适用于多模式智能振动压路机,也适合于一般的振动压路机。Several representative domestic and foreign on-line evaluation methods for compactness of material compaction are described.It is pointed out that,for most existing on-line evaluation methods of compactness,only vertical vibratory performance of a compacting system is considered while the coupling vibratory performance of the compacting system in horizontal direction is ignored.A new method to set up model with multiple vibratory eigen-values in vertical and horizontal directions of the compacting system is adopted to evaluate material compactness on-line.With the method,coupling vibration influence on the compacting system resulted by any factors arc removed.It is particularly suitable to intelligent vibratory compactor with multi-modes and also compatible for common vibratory compactors.
