土壤固化剂具有高效、低耗和节约能源的优点,是一种新型工程材料。而软土具有土质疏松、天然含水量高、透水性差、压缩性高等不良特性,在软土地基上进行工程施工时,往往会造成地基承载力不足、不均匀沉降等问题,故采用土壤固化剂对软土地基进行加固处理是一种有效的手段,具有广阔的应用前景。本文首先介绍了土壤固化剂的定义、分类和作用机理;然后介绍了土壤固化剂的国内外研究现状及适用范围;重点阐述了土壤固化剂在软土地基处理方面的应用以及相关研究成果;最后分析了当前软土固化剂研究中存在的问题,并针对软土地基采用固化剂时进一步研究方向。 Soil stabilization is a new type of engineering materials with the character of high efficiency, low consumption and energy saving. The soft soil has the properties of loose, high natural water content, poor water permeability and high compressibility. When the construction is carried out on the soft soil ground, the uneven settlement may occur due to the insufficient bearing capacity of soft soil foundation. Therefore, soil stabilization is an effective method to reinforce the soft soil foundation, and then the bearing capacity of the foundation can be increased. In this paper, the definition, classification and mechanism of the soil stabilization were firstly introduced. Then, the research progress and scope of application of soil stabilization were given in details. After that, the application of soil stabilization and related research results in soft soil foundation treatment were further introduced and discussed. Finally, some drawbacks existing in the research of soft soil stabilization were analyzed, and future research was given.
