Application of In-situ Solidification Technology in Shallow Treatment of Ultra-deep Silty Mud
Due to the characteristics of high fluidity and low bearing capacity,the treatment of ultra-deep muddy soil foundations often faces issues such as long construction periods,high costs,and susceptibility to instability.To improve the existing treatment methods for ultra-deep muddy soil foundations,particularly addressing the deficiencies in relevant theoretical calculations,this paper proposes a shallow in-situ solidification treatment scheme for such foundations,based on the case study of the green renovation of the muddy area in the City Exhibition Garden of the 11th Jiangsu International Horticultural Exposition.A detailed analysis of the bearing capacity and settlement calculation of the composite foundation with in-situ solidified piles is conducted,outlining a complete calculation process.Furthermore,on-site loading tests are performed to further verify the feasibility of the proposed scheme,providing technical references for similar engineering projects.
