Abstract

Many frost heave theories and models have been proposed to explain the frost heave phenomenon. In the present study, systematic frost heave experiments were conducted under various temperature gradients and freezing rates, and the relationships between the water intake rate and the freezing front, freezing rate, temperature gradient in the frozen zone, and temperature of the ice lens growth surface were investigated. The experimental results showed that there is a linear relationship among the water intake rate, freezing rate, and temperature gradient, and that there is also a linear relationship between the water intake rate and the temperature of the ice lens growth surface. Based on these findings, the validity of the existing frost heave models was evaluated. The results of this study revealed that the water intake rate to the freezing front cannot be expressed only by the temperature gradient in the frozen fringe. In addition, a model in which the rate of the water intake into the ice lens is determined by the hydrodynamic resistance of the water flow in the frozen fringe cannot explain the experimental results well. With a kinetic model, in which the water intake rate is determined by the chemical potential difference between the ice lens and the nearby water film, it was found that the calculated results and the actual measurement results corresponded well when the self-diffusion coefficient of the water film near the ice lens was used as a fitting parameter.

期刊介绍： Soils and Foundations is one of the leading journals in the field of soil mechanics and geotechnical engineering. It is the official journal of the Japanese Geotechnical Society (JGS)., The journal publishes a variety of original research paper, technical reports, technical notes, as well as the state-of-the-art reports upon invitation by the Editor, in the fields of soil and rock mechanics, geotechnical engineering, and environmental geotechnics. Since the publication of Volume 1, No.1 issue in June 1960, Soils and Foundations will celebrate the 60th anniversary in the year of 2020. Soils and Foundations welcomes theoretical as well as practical work associated with the aforementioned field(s). Case studies that describe the original and interdisciplinary work applicable to geotechnical engineering are particularly encouraged. Discussions to each of the published articles are also welcomed in order to provide an avenue in which opinions of peers may be fed back or exchanged. In providing latest expertise on a specific topic, one issue out of six per year on average was allocated to include selected papers from the International Symposia which were held in Japan as well as overseas.
