摘要
通过大量调查试验 ,阐述了腾格里沙漠粉土的物理力学特性。揭示了粉土的湿陷变形特性 ,提出了粉土成分含量是引起粉土湿陷变形的主要因素。并得出了按规定施工工况压实后 ,粉土能够达到压实质量要求 ,且具有较高的强度和水稳性 ,可保证建筑物安全稳定的科学结论。
Based on large number of experiment and investigation, the physical and mechanical properties of silt-sand in Tengeli desert zone are clarified in this paper. And the characteristics of collapse deformation by wetting are also revealed. It is proposed that it is the granule composition of silt-sand that mainly causes the collapse deformation by wetting. Finally, it is concluded that the silt-sand foundation can meet the compaction quality requirement after being compressed according to the construction procedure prescribed, and it has enough strength and water stability, and can assure the hydro-structures safety and stability.
