The paper presents frost heave experimental studies performed on the saline soil. The frost heave properties of soil are important for project construction in seasonal frozen area. The effects of initial water content and salinity on the frost heave properties are investigated, and the experiments on sodium carbonate saline soil indicate that the initial water content of the saline soil is mainly factor for frost heave, salt has inhibitory effect on frost heave, and the normal frost heave rate is proportional to the moisture content of soil. In addition, the study shows that the frost heaving stress is proportional to the moisture content of saline soil, and a high salt content can reduce the stress, and the frost heave stress and normal frost heaving ratio have a clear nonlinear relationship. Identifying the frost heave properties provides basic data support for the engineering construction in the seasonal frozen area, and is conductive to understanding the frost heave mechanism of saline soil.

Abstract


The paper presents frost heave experimental studies performed on the saline soil. The frost heave properties of soil are important for project construction in seasonal frozen area. The effects of initial water content and salinity on the frost heave properties are investigated, and the experiments on sodium carbonate saline soil indicate that the initial water content of the saline soil is mainly factor for frost heave, salt has inhibitory effect on frost heave, and the normal frost heave rate is proportional to the moisture content of soil. In addition, the study shows that the frost heaving stress is proportional to the moisture content of saline soil, and a high salt content can reduce the stress, and the frost heave stress and normal frost heaving ratio have a clear nonlinear relationship. Identifying the frost heave properties provides basic data support for the engineering construction in the seasonal frozen area, and is conductive to understanding the frost heave mechanism of saline soil.
