The Application of Local Softer Foundation Replacing Treatment to Coarse Sandy Stratum |
| |
| Abstract: | Taking the construction of replacing treatment to local softer foundation in coarse sandy stratum in a first-class terrace,this article expresses that the replacing treatment is economic and practical to this stratum.The applied field of replacing treatment and natural foundation has been extended,and the difficult points of pile base construction have been avoided.The cost and construction time has been saved.This article also summarizes the construction experience on replacing treatment to gradated sand and stone. |

| Keywords: | replacing treatment coefficient of compaction maximum dry density graded sand and stone |
