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,固化处理是其最常用也最有效的方法之一。深入理解固化软土的固化机理、强度特性和耐久性的影响机制是确保固化处理滨海软土地基维持长期安全稳定的关键前提。通过对水泥固化滨海软土的强度和耐久性进行综述,阐明水泥对滨海软土的多尺度耦合固化机理,讨论当前针对滨海软土固化体研究的不足,探讨具有前沿性的潜在研究建议,为后续科学研究和工程应用推进提供新的思考和思路。
A large area of deep coastal soft soil layer is widely distributed in the coastal area.It has the remarkable characteristics of'three-high,two-low,and one-long characteristic'with high water content,high compressibility,high organic matter content,low bearing capacity,low permeability,and long deformation stability time.Solidification treatment is one of the most used and most effective methods.An in-depth understanding of the solidification mechanism,strength characteristics,and durability of solidified soft soil is crucial for ensuring the long-term safety and stability of solidified coastal soft soil foundation.The strength and durability of the cement solidified coastal soft soil are reviewed.The multi-scale coupling solidification mechanism of cement on coastal soft soil is clarified.The shortcomings of the current research on solidified coastal soft soil are discussed,and the potential research suggestions with cutting-edge are discussed,which provides new thoughts and ideas for the follow-up scientific research and engineering application.
