Reinforcement characteristics of ultra-soft ground in Tianjin Port

摘要: 超软土的高压缩性、低渗透性和难固结特性决定了此类土体的地基处理十分困难,一般方法难以达到理想的加固效果。针对天津某工程的超软土,详细阐述了地基加固的设计方法和施工工艺过程;通过室内试验并结合现场监测检测,充分研究了超软土在不同加固阶段的物理特性、变形特性、固结特性和强度特性。结果表明加固后的超软土地基可以达到工程使用要求,可供类似工程借鉴。Abstract: Due to its high compressibility, low permeability and low consolidation property, the treatment of ultra-soft soil is very difficult, and the common method is hardly effective. For the ultra-soft soil in Tianjin Port, the design method and construction technique are clarified. According to the indoor experiments and in-situ inspection, the physical, deformation, consolidation and strength properties of ultra-soft soil at different stages are analyzed. The results show that the ultra-soft ground after reinforcement can satisfy the engineering requirements, which can be referred for the similar projects.
