Continuous Dynamic Monitor Technology on Subgrade Compaction Quality

In order to solve the problem that the compaction quality of coarse-grained soil is difficult to control, the known method of control to compaction quality was analyzed. Dynamics monitor method whose trait is continuously testing information of the subgrade resistance change was presented. According to the dynamics analysis of the interaction between road roller and subgrade structure, authors put vibratory roller as testing target and adopted system identification theory and dynamic testing technology. By continuous testing of the interaction between compaction machine and subgrade structure, authors got the information of resistance which could reflect the change of structure compacting state. Authors appraised the change of structure compacting state by resistance change of subgrade in its forming process. By this way, continuous quality monitor in field during the compaction process was accomplished. It is different from the method of CMV which is popular in foreign countries, and is wider in applied range, also is convenient for field test and is more suitable to compaction quality monitor of coarse-grained soil.
