摘要
自重湿陷性黄土是指土样在上覆土的饱和自重压力作用下引起湿陷性变形,该变形方式具有变形量大、变形速度快及建筑物容易失稳等特点,对建筑物危害特别大;本文立足具体工程试验,通过不同地基处理方式的对比分析,得出了水泥土挤密桩在自重湿陷性地基处理中的可行性研究和经济性指标,对同类工程具有借鉴意义。
Self-weight collapsible loess refers to the collapsible deformation caused by the soil sample under the saturated self-weight pressure of the overlying soil. The deformation mode has the characteristics of large deformation, fast deformation speed and easy instability of the building, which is particularly harmful to buildings. With the help of specific engineering and comparative analysis of different foundation treatment methods, the feasibility and economic indicators of cement-soil compacted piles in self-weight collapsible foundation treatment are obtained, which provides reference for similar projects.
