Abstract
This paper presents a case history of instrumented house with shallow foundation on the seasonally frozen ground. Variations of the soil frost penetration, the soil temperature, the cracks of the house, the displacements and the contact pressure on the base were systematically observed during freezing and thawing periods. It has been confirmed that the main reason why the cracks of the houses with shallow foundations occurred is that the development of the frozen depth is not uniform and the frost heaving and the redistribution of the contact pressures are unequal. This paper puts forward the principle of the effective depth of frost heaving and a new concept of foundation design method, which is adopted in the Chinese Code TJ7-74.

The Behavior of House on Seasonally Frozen Ground
This paper presents a case history of instrumented house with shallow foundation on the seasonally frozen ground. Variations of the soil frost penetration, the soil temperature, the cracks of the house, the displacements and the contact pressure on the base were systematically observed during freezing and thawing periods. It has been confirmed that the main reason why the cracks of the houses with shallow foundations occurred is that the development of the frozen depth is not uniform and the frost heaving and the redistribution of the contact pressures are unequal. This paper puts forward the principle of the effective depth of frost heaving and a new concept of foundation design method, which is adopted in the Chinese Code TJ7-74.
