| Abstract: | Taking the engineering of peat soil subgrade for railway hub in Kunming reinforced by cement mixing piles as an example, the engineering properties of peat soil foundation in Dianchi was introduced. Then through compaction test and unconfined compressive strength test, the optimum water content, the maximum compactness and the unconfined compressive strength of the cement-peat soil under different cement contents on the construction site were studied; then, the effects of initial water content, compactness and concrete age on the unconfined compressive strength of cement reinforced peat soil were discussed. The results can be taken as important reference to actual enzineerin~. |
