摘要
研究了强膨胀土的动参数φｄ、ｃｄ，建立了重塑土在循环荷载作用下长期变形的数学模型，用该式的计算值和实测值进行比较，其结果令人满意。对工程应用有指导意义。
The dynamic shear strength of the swelling soil is studied. According to the experimental data, a mathematical model on long term deformation of the remolded swelling soil under dynamic load is suggested. It can be seen that the dynamic strength is dependent on the static strength. The calculated values of the formula of the model are examined with the experimental data, the result is satisfied and is useful to engineering construction.
