| Abstract: | On the basis of the project of saline soil roadbeds treatment in the Jin-Shan Expressway,the physical properties,mechanical properties and chemical properties of saline soil with different depth in the roadbeds are introduced.In order to investigate the effects of curing time,cement content,salt content,load-velocity on the strength behavior of the cement-stabilized saline soil,a series of physical tests and unconfined compressive tests are performed on cement-stabilized saline soil.The reiforcement mechanism of saline soil stabilized by cement is primarily discussed,the probability of saline soil roadbeds treated by cement-mixing pile is analyzed,and then the reasonable mixture ratio to satisfy the design and construction of cement-mixing pile in saline soil highway is proposed. |
