| Abstract: | Based on cement mixing pile of field trials for the Yanglin lock project,by the two constructiontechnologies of cement mixing piles,the effect of synthetic pile mixed with the clay and cement is comparativelyanalyzed,while the plasticity index of the clay is greater than 25. Experiments indicate that some key technicalparameters of the piles of construction technology of＂Four Stir Three Spray＂,such as cement doses and unconfinedcompressive strength,are better than that of the construction technology of＂Two Stir One Spray＂,and the quality ofthe former satisfies with the requirements of the projects. |
