| 摘 要： | 在地质条件复杂、水量贫乏的湿陷性黄土场地建造大型甲类储罐,要求在有效影响深度范围内完全消除湿陷量.结合实际工程,通过施工试验研究得出:预增湿后采取高能级强夯能有效改善场地土的各项参数,消除场地土湿陷量和提高承载力作用显著,但结合大型储罐基础对地基不均匀沉降十分敏感的特殊性,其处理效果以及对土体的改善程度是有限的.

| Abstract: | It is required to eliminate sedimentation totally in valid depth when large storage tanks is set up on collapsed loess with complicated geological conditions.Based on actual project,the construction experimental research shows that the prewetting & high-energy dynamic consolidation of collapsed loess can effectively improve the soil parameters and increase the bearing capacity of soil significantly.However,because the large storage tanks very sensitive to the uneven sedimentation of foundation,its effects and the improvement of the soil is limited. |
