摘　　要：不同荷载下软土随时间的变形特征是软基沉降设计的重点。通过进行室内高压固结试验,求得不同荷载下的固结系数及正常固结状态下软土的前期固结压力,分析软土屈服前后固结系数差异及变化特点,为珠三角洲软土的力学特性研究提供可供参考的建议。The foundation settlement is designed to focus on deformation characteristics of soft clay under different loads over time. According to the coefficient of consolidation and preconsolidation pressure under the oedometer test, we analyze the variation characteristics of coefficient of consolidation before and after normally consolidated soft clay. Relevant suggestions are put forward to serve as reference for the research on Zhujiang delta continent soft clay＇s mechanical characteristics.
