摘要
应用动三轴仪对厦门软粘土做了一系列的振陷试验,建立了淤泥质软粘土的振陷经验公式。试验结果表明,该类软粘土动孔压的发展规律性差,具有较强的结构性,其残余应变受动应力的影响较大,当残余应变达到5 % 左右时,软粘土的结构发生破坏。
A series of seismic depression tests about the soft clay of Xiamen were conducted using dynamic cyclic triaxial apparatus. According the result of tests, a residual strain formula of the soft clay was established. The experimental results show that the dynamic pore water pressure rises much slowly. The structural characteristics of the soft clay is very strong. The residual strain of the soft clay is much affected by dynamic stress. When residual strain reaches 5% or so, the structure of the soft clay is damaged.
