Abstract: This paper presents a case history of using a heavy vibratory to eliminate the potential wetting settlement of loess soil deposits in the Xi'an Central Container Station Project. The principles of the heavy vibratory rolling technique are briefly introduced. After the rolling compaction, the degree of compaction bearing capacity and the modulus of compression have increased and the wetting settlement of the loess soils can also be effectively eliminated.
