%X 为了建立振动轮振动加速度与路面压实度之间的关系以检测路面压实，分析了振动轮与路面压实材料之间的动力学关系，建立了振动压路机？猜访嫦低扯？力学模型，提出了路面压实度连续检测技术的设计方案，研究了采用振动轮垂直加速度有效值表示压实度的技术及方法，并进行了现场试验。研究结果表明：垂直振动加速度与路面材料刚度正相关，与阻尼负相关；路面基层、下面层、中面层的压实度与振动轮垂直加速度有效值之间存在较好的正相关对应关系，其相关系数R2分别为0.900 2、0.934 0、0.931 4；该连续检测系统可方便准确地进行测量，实时有效地控制路面质量，提高了压实效率。<br>In order to establish the relationship between vibration acceleration and the degree of pavement compaction for the detection of compactness, this paper analyzed dynamic relationship between vibration compaction and the pavement compacted material, and established dynamic mathematical model. On this basis the automatic and continuous detection technology of pavement compaction degree was put forward. Then the technique and method using vertical effective value of vibration acceleration to represent compaction degree was studied and the field test was conducted. The results show that the vertical vibration acceleration is positively related to pavement stiffness, and negatively related to damping. The compactness of base course, middle pavement and top pavement is positively related to wheel vertical vibration acceleration RMS, and the correlation coefficients R2 are 0.900 2, 0.934 0, and 0.931 4. The continuous monitoring system can easily and accurately measure pavement compactness, control the quality of road in real time effectively, and thus improve the efficiency of compaction
