石灰改良膨胀土的研究(二)——改良效果及改良机理

A Study of Improving Expansive-soil with Lime(Ⅱ)——Effects and Mechanism of the Improvement

在文[1]的基础上,通过试验和理论分析。从土的膨胀性、收缩性、强度、和稳定性四个方面评价了石灰改良膨胀土的效果。并应用化学热力学理论,论证了灰土之间的化学反应可能性、进行的程度及所要求的条件。

On the basis of Ref[1] .through tests and theoretical analysis,the effects of improving expansive-soil by lime are discussed according to the four aspects- the expansibility,the contratibil-ity, the strength and the stability of the soil. The occuring possibility, the proceeding extent and the required condition of the chemical reaction between soil and lime are verified based on the theory of chemical thermodynamics.
