The stack yard of a terminal project in Tanzania uses blown-filled land，mainly for temporary storage of light cars，and applies coral soil as the base back filler.We carry out the comparative analysis of Chinese and British standards of water CBR（California bearing ration）test，on-site CBR and compaction test of the back fillers，such as coral soil，coral stone and coral stone adding cement，and summarize their rules.The results show that for stack yards with lower bearing capacity requirements designed by British standard，the coral soil mixed with clay can be used as the base layer.The coral soil mixed with a certain amount of clay can meet the indoor water CBR value under the design compaction requirements.The coral soil back filler can meet the requirements for light container yards due to its high porosity and low strength，while heavy container yards must be investigated separately.
