Research Progress and Review on the Strength and Durability of Cement Solidified Coastal Soft Clay

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.
