【摘要】 利用线性双曲迭代函数系统(LHIFS)理论以及以LHIFS为基础的分形插值方法,拟合了季节冻土区非等温条件下土体的冻胀过程,从而可以实现对冻胀量的预报,并与实测结果和理论计算结果进行了对比。结果表明:对冻胀过程采用分形逼近是可行的,逼近结果与实际情况相吻合。更多还原

【Abstract】 Using LHIFS and fractal interprolation, the process of frost heave in soil is imitated under the condition of transient temperature. Thereby the prediction of frost heave is come true. At the same time, the approximation result contrast with that of survey and calculation, which indicate that the approximation result is identical to fact instance. It is feasible to fractal approximation is used to imitating the process of frost heave in soil.更多还原
