Growth Condition of an Ice Layer in Freezing Soils Under Applied Loads: 1. Experiment

A series of freezing tests on Kanto loam were conducted under various overburden pressures to find the steady growth condition of a segregated ice layer. The steady growth condition was found to be determined by the absolute value of the temperature gradient of the unfrozen part of the soil a sub u...

Description
Summary:A series of freezing tests on Kanto loam were conducted under various overburden pressures to find the steady growth condition of a segregated ice layer. The steady growth condition was found to be determined by the absolute value of the temperature gradient of the unfrozen part of the soil a sub u near the 0 deg C isotherm and that of the frozen part of the soil alpha sub f near the warmest end of an ice layer under given hydraulic conditions and applied effective pressure sigma This is the first of a two-part presentation on the subject; the analytical aspects of the study are presented in a second report.
