建筑工程地基加固效果受土体腐殖酸的影响。根据国内外土壤腐殖酸现有研究成果及方法,通过对不同水泥掺量、不同地域水泥土的对比性试验,运用灰色关联分析方法,以确定腐殖酸组分对无侧限抗压强度的影响。由水泥土无侧限抗压强度试验数据所建立数学模型显示,其预测模型及效果精度完全满足工程的需求。
The reinforcing effect of the foundation of the project is affected by the humic acid of soil. According to the existing research results and methods of soil humic acid at home and abroad, through the comparative experiments of different cement content and cement soil in different regions, the gray relational analysis method was used to determine the effect of humic acid composition on unconfined compressive strength Impact. The mathematical model established by the unconfined compressive strength test data of cement soil shows that the prediction model and the accuracy of the results fully meet the requirements of the project.
