Intelligent detection method and system for compaction degree of road base
The invention discloses an intelligent detection method and system for the compaction degree of a road base, and the method comprises the following steps: 1, collecting engineering field data, obtaining a relation curve of the moisture content and the dry density of road base filler, and obtaining the maximum dry density and the optimal moisture content according to the relation curve; step 2, determining a compactness index value of a construction section, wherein the index value is comprehensively considered and determined according to specification requirements in combination with on-site actual conditions, equipment factors of the vibratory roller and other conditions; step 3, establishing a multiple linear regression model of the ratio of the compaction degree to the frequency domain harmonic wave, the water content and the speed; and 4, the compaction condition of the construction section is detected in real time and fed back to operators in time. According to the method, the vibration signals are collected and processed, and the multiple regression model is established by using the harmonic ratio and the rolling parameters, so that the real-time monitoring and evaluation of the filling compaction degree of the road foundation are realized. The method has the characteristics of real-time performance, accuracy and intelligence, and can provide an effective quality control means for road base construction.
本发明公开了一种道基压实度智能检测方法及系统，包括以下步骤：步骤一、工程现场数据采集，得到道基填料的含水率与干密度的关系曲线，根据关系曲线得到最大干密度与最佳含水率；步骤二、确定施工段的压实度指标值，该指标值依据规范要求，结合现场实际情况及所用振动压路机的设备因素等情况综合考虑确定；步骤三、建立压实度与频域谐波比值、含水率、速度的多元线性回归模型；步骤四、施工段压实状况实时检测，并及时反馈给作业人员。本发明通过采集振动信号并进行处理，利用谐波比值和碾压参数建立的多元回归模型，实现了对道基填土压实度的实时监测和评估。该方法具有实时性、准确性和智能化的特点，可以为道基施工提供有效的质量控制手段。
