摘要
通过海积软土的室内多级加荷一维固结蠕变试验,研究不同应力水平下的软土随时间的变形发展规律、次固结系数的变化规律和次固结变形与加载历史的关系,相关试验成果为正确地预测软土地基沉降随时间的变化规律和减少工后蠕变沉降计算的合理化模式提供试验依据。
By indoor multi -stage loading one -dimensional consolidation creep test of marine soft soil , under different stress levels ,this paper analyzes the soft soil deformation development law over time , the change rule of secondary consolidation coefficient and the secondary consolidation deformation relationship with different loading history . Relevant test results provide experiment basis for correctly forecasting the change rule of soft soil foundation settlement over time , andfor the rationalization model with reducing post construction creep settlement calculation .
