| 英文摘要 | Applying cohesive soil to wrap fine sand on a subgrade slope is a new type of filling technology in railway subgrade construction. The choices of specific compaction methods and quality evaluation indicators are critical for achieving high compaction quality. In this paper, a series of field rolling tests with different compaction machines was carried out in the experimental section of China Menghua railway. Then, the compaction quality was gauged considering different indexes such as relative density (D-r), degree of compaction (K), coefficient of subgrade reaction (K-30) and dynamic modulus of deformation (E-vd). It is shown that adopting clayey soil (namely, wrapping soil) to cover a sandy roadbed slope can keep the internal humidity of the subgrade stable. For compaction of the fine sand used in this study, it was better to select a bulldozer to squeeze along the longitudinal and horizontal directions alternately six times, and the lift thickness was set at 35 cm. The results show a linear relationship between E-vd and K-30 for the sand. The application of E-vd as a substitute for K-30 in the compaction evaluation of sand subgrade can lead to significant efficiency. |
