摘要

沿海地区广泛分布大面积的深厚滨海软土地层，具有含水率高、压缩性高、有机质含量高、承载力低、透水性低和变形稳定时间长的“三高两低一长”的显著特征，化学固化是其最常用也最有效的处理方法之一。水泥固化滨海软土面临耐久性差、能耗和碳排放高的挑战。碱激发地聚物是一种绿色低碳、高效环保的胶凝材料，探究其对滨海软土的固化效果和固化机制成为岩土工程领域的研究热点。然而，目前对地聚物固化滨海软土的研究仍然存在一些亟待解决的问题。对碱激发地聚物滨海软土固化体的强度和水稳定性进行了归纳和总结，阐明了碱激发地聚物对滨海软土的多尺度耦合固化机制，讨论了当前针对地聚物滨海软土固化体研究的不足，分析了碱激发地聚物固化滨海软土的可持续性，探讨了具有前沿性的潜在研究建议，为碱激发地聚物滨海软土固化体的后续科学研究和应用推广提供新的思考和思路。

Abstract

A thick layer of soft clay is widely distributed in the coastal area. Coastal soft clay is characterized by high compressibility

high water content

high organic matter content

low bearing capacity

low permeability and prolonged stabilization time. Solidification treatment is one of the most popular and effective methods for improving the mechanical properties of coastal soft clay. Cement solidified coastal soft clay faces challenges such as poor durability

high energy consumption and carbon emissions. Alkali-activated cementitious material (AACM) is a green and low carbon cementitious material. Utilization of AACM for stabilizing coastal soft clay has become a research focus in the field of geotechnical engineering. However

several critical issues remain unresolved in the study of AACM solidified coastal soft clay. This study reviews the strength and water stability of AACM solidified coastal soft clay. The multiscale coupled solidification mechanism of AACM in coastal soft clay is elucidated. The shortcomings of current research on AACM solidified coastal soft clay are discussed. The sustainability of AACM solidified coastal soft clay is analyzed

and potential research suggestions are discussed. This study can provide new ideas and insights for the subsequent research and promotion of AACM solidified coastal soft clay.
