摘要
工程实践表明 ,与单纯用水泥加固相比 ,用磷石膏与水泥配合加固软土地基可大幅度提高加固土强度 ,且拓宽了水泥加固技术适用的土质条件范围 ,技术、经济和环境效益显著。对不同的土质 ,磷石膏的增强效果差异很大。在多土层地基施工时 ,应注意固化剂配合比对各土层的适用性。采用正确的加固土强度试验方法才能得到对磷石膏增强效果的正确评价。
Engineering practice proved that:the strength of stabilized soil stabilized by cement with phosphorous gypsum is much higher than by cement only.It broadens the scope of soil suitable to be stabilized and brings remarkable technical,economic and environmental benefits.The strengthening effect to different soil by phosphorous gypsum is different,so the ratio of stabilizers should be adjusted when applied to multi-layer soil.Correct evaluation to strengthening effect could be obtained if,and only if,proper test method is used.
