In order to promote the wide application of continuous compaction control technology in China, the continuous compaction control technical regulations of various countries and regions in the world are taken as research objects, and the technical characteristics and application conditions of various countries' regulations are compared and analyzed. The current continuous compaction control technology is analyzed. The main quality acceptance methods and standards, summed up the application experience of the technology around the world. The results show that the comprehensive evaluation of the comprehensive evaluation of compaction degree, compaction uniformity and compaction stability is the trend of quality control standards development. The calibration method is mainly used. The problem of water content of fine particle fillers has a significant impact on continuous compaction control and has been widely recognized. The water content of the filler needs to be controlled in engineering applications. The basic theory of continuous compaction control method is becoming more and more mature, and the development direction of the actual compaction problem is gradually developed. The accuracy requirement of continuous compaction control is gradually improved. The weak area identification method is supplemented by the incremental method of measurement. The reasonable selection of evaluation methods for engineering characteristics is an effective way to promote the successful application of continuous compaction control technology.
