Abstract: In order to realize the intelligent evaluation capability of the quality uniformity of the subgrade compaction construction, a method for evaluating the quality of the subgrade compaction construction based on the multi-distribution sensing information feature extraction is proposed. A multi-dimensional sensor is adopted for detecting the quality of the roadbed compaction construction quality. The quality uniformity distribution identification model of the roadbed compaction construction is constructed. The maximum likelihood estimation method is adopted to perform the position calibration, and the statistical analysis of the quality uniformity of the subgrade compaction construction. By using the multi-resolution feature extraction and the large data mining method, the linear fitting of the statistical characteristics of the quality uniformity of the subgrade compaction construction is obtained, and the quality uniformity evaluation of the subgrade compaction construction is determined according to the fitting result. The optimal design of the automatic monitoring system for the quality of the subgrade compaction construction is carried out under the environment of the ARM embedded microprocessor. The test results show that the accuracy of the quality uniformity of the subgrade compaction construction is high, and the real-time positioning and detection performance of the quality uniformity of the subgrade compaction construction is good.
