土壤固化剂的固化机理与研究进展

Stability Mechanism and Research Progress of Soil Stabilizer

土壤固化剂属于一种新型的绿色建筑材料,其施工简单且工程适应性高,提高了施工效率,减少了社会资源的利用,有效保护了生态环境。然而,由于土壤固化剂种类繁多,其适用范围、作用效果也不尽相同,近几年来研究者主要针对不同类别土壤固化剂的固化机理以及其对土壤性能的影响进行研究,并取得了丰硕的成果。通过微观与宏观相结合,不断探究各种变量下固化土性能变化,改进配比,在充分发挥土壤固化剂优势的同时,使其更好地应用在实际工程中。本文分析了无机类、离子类、有机类和生物酶类四种不同类别土壤固化剂的固化机理,并对其力学性能、耐久性能和动力特性进行了归纳,在此基础上总结了不同类别土壤固化剂的优缺点与适用范围,提出了部分研究建议,以期为后续土壤固化剂的制备与研究提供部分参考。

The soil stabilizer is a new type of green building material with simple construction and high engineering adaptability,which not only improves the construction efficiency,but also reduces the use of social resources and effectively protects the ecological environment.In recent years,the stabilization mechanism of different types of soil stabilizers and their effects on soil performance have been extensively studied,because there are many types of soil stabilizers,and their scope of application and effects are also different.Finally,a lot of results have been achieved.Researchers are constantly studying the changes in the properties of stabilized soils under various variables and improving the ratio of soil stabilizer by combining micro and macro.Research can fully demonstrate the advantages of soil stabilizers and be better applied in actual projects.This paper analyzes the solidification mechanism of four different types of soil curing agents,including inorganic,ionic,organic and biological enzymes,and summarizes their mechanical properties,durability and dynamic properties.On this basis,the advantages,disadvantages,and scope of application of different types of soil stabilizers are summarized.Finally,some research suggestions are put forward in order to provide some reference for the preparation and research of subsequent soil stabilizers.
