摘要
对原状软土做了大量的分级加载室内一维次固结试验,通过对软土次固结变形的试验分析,得出原状软土的次固结系数以及主、次固结分界点的变形时间,根据试验结果得到原状土的次固结系数与固结压力及固结比之间的关系,用最小二乘法拟合出次固结系数与固结比之间的经验关系表达式。
The laboratory 1-D secondary consolidation tests of soft soils of undisturbed through incrementation has been done. Through analyse of secondary consolidation deformation, coefficient of secondary consolidation of soft soils of undisturbed has been educed, deformation time dividing point of main consolidation and secondary consolidation. The relationship on secondary consolidation inefficient and PCR and pressure. The experiment equation on coefficients of secondary consolidation and PCR were achieved by least squares.
