Abstract：
To research static compaction deformation characteristics of different thickness red sandstone soil, static load compaction tests were conducted by using electronic universal testing machine. Force - displacement relations of red sandstone filling were obtained and the effects of thickness on static compaction deformation characteristics were analyzed. The results show that in the compaction test of red sandstone filling, relationship between the stress and displacement is exponential. Relationship between the compression modulus and stress terminal value is linear . Three stages are included by the following order during compaction process：compaction stage，broken stage and stable stage. In the process of static compaction, strain growth exist a turning point.
