Solidification treatment method suitable for strong chlorine salt soft soil
The invention discloses a curing treatment method suitable for strong chlorine salt soft soil, which is characterized in that ordinary Portland cement is used as a main curing agent, fly ash is used as an auxiliary curing agent, and a small amount of calcium hydroxide is added to form a composite curing agent. The method focuses on the high-chlorine-salt soft soil, and the problems that the chlorine salt soft soil treatment effect is not obvious, the pertinence is not high, the mixing amount of a curing agent is large, the composition of the curing agent is complex, the curing agent is difficult to apply to practical engineering, and the economical efficiency is low are solved. The highest chlorine salt content for actual curing engineering is refreshed, the highest chlorine salt content of the curable soft soil is increased to 7.5%, and the construction efficiency and the engineering operability are improved. Indoor experiment results show that the method greatly meets the engineering construction requirements in the aspects of improving the high-chlorine-salt soft soil matrix and improving the bearing capacity and stability of the soil matrix, and has high application value and popularization prospects.
本发明公开了一种适用于强氯盐软土的固化处理方法，以普通硅酸盐水泥为主固化剂，粉煤灰为辅助固化剂，添加少量氢氧化钙组成复合固化剂。本方法着眼于高氯盐软土，解决了传统固化手段处理氯盐软土效果不明显、针对性不强、固化剂掺量大、固化剂组成复杂、难以应用到实际工程、经济性低等问题。刷新了可用于实际固化工程的最高氯盐含量，将最高可固化软土氯盐含量提升至7.5％，提高了施工效率和工程操作性。通过室内实验结果表明，本方法在高氯盐软土土基改良、改善土基承载能力和稳定性方面均极大的满足了工程建设要求，具有较高的应用价值与推广前景。
