摘要
随着环保要求的提高和自然资源的短缺,工业废弃料改性不良土体成为缓解道路材料短缺和加速绿色建筑材料开发的重要途径。本文旨在系统地综述工业废渣在土体改良中的应用,分析其物理化学性质、改良作用机制,并探讨其在实际应用中的研究进展与面临的挑战。通过对赤泥、钢渣、磷石膏等废渣的复合激发技术进行详细分析,介绍了单一及复合废渣的协同效应与改良效果。研究表明,工业废渣不仅能够显著提升软土地基、膨胀土及污染土壤的工程性能,而且为解决传统土体改良材料资源短缺提供了新的思路。然而,当前的研究仍然面临废渣改良土体长期稳定性与环境安全性不足的问题,特别是在重金属释放风险及改良体系长期效应的评估方面。为此,本文建议在未来的研究中,进一步加强废渣改良土体的长期性能监测、环境风险控制及实际工程应用验证。通过这些努力,可以推动工业废渣在土体改良领域的绿色可持续发展。
With the increasing environmental requirements and the shortage of natural resources,the modification of poor soils with industrial waste residues has become an important approach to alleviate the shortage of road materials and accelerate the development of green building materials.This paper aims to systematically review the application of industrial waste residues in soil improvement,analyzing their physical and chemical properties,improvement mechanisms,and the research progress and challenges in practical applications.Through a detailed analysis of the composite activation techniques of waste residues such as red mud,steel slag,and phosphogypsum,this paper introduces the synergistic effects and improvement results of both single and composite waste residues.Research shows that industrial waste residues can significantly enhance the engineering performance of soft soil foundations,expansive soils,and contaminated soils,and provide new ideas for solving the resource shortage of traditional soil improvement materials.However,current research still faces challenges related to the long-term stability and environmental safety of waste residue-modified soils,especially in terms of heavy metal release risks and the evaluation of long-term effects of the improvement system.Therefore,this paper suggests that future research should further strengthen the long-term performance monitoring,environmental risk control,and practical engineering application verification of waste residue-modified soils.These efforts can promote the green and sustainable development of industrial waste residues in the field of soil improvement.
