摘要

Many studies have been conducted on unfrozen soil, while only limited studies have been done so far on frozen soil. The construction on glacial or frozen soils is quite unpredictable as we don’t have a detailed study of frozen soils as we have for soils under normal room temperature. For constructions at room temperature, a plethora of experimental research and research data about soil is accessible. A detailed study is required to be performed to analyze the soil under frozen conditions to identify various characteristics of frozen soils. Only a handful of research work has been conducted on the mechanical properties of frozen soil. However, there are very few studies on the fundamental parameters of frozen soil, such as porosity, dry density, bulk density, degree of freezing, and void ratio. In this paper, the primary objective is to perform experimental studies on frozen soil and to obtain various interrelationships between individual soil parameters between unfrozen and frozen soil. This paper consists of modelling the soil surface covered with plastic plates. The experimental model samples have been placed in beakers with different densities and a glass plate at the top so as to replicate practical site situations in a deep freezer. After the calculation of different factors, such as the water content, the void ratio, and the porosity for the ultimate frozen temperature of –28 ℃, mathematical relationships were formed with the help of given parameters at existing room temperature. To obtain the experimental modelling data, “Eureqa software” has been used to utilize the data so obtained in laboratories and will determine the mathematical relations between the existing soil parameter at a given room temperature. So, in this study, efforts are made to formulate relationships for different soil parameters at completely frozen and unfrozen states.
