| Based on the achievements of cement deep mixing method, and combining the features of Lianyungang soft soils, the laboratory research was carried out on the different ratios of cement and soils, in which the cement was basic solidifier, and the adaptability of early strength accelerators and water reducers was also analyzed in this thesis. Referring to the laboratory test results, the field trial construction and the cement deep mixing columns quality checking were done to study the plan of cement-soil ratio and the construction techniques. The following conclusions could be drawn from this experimental... |
