METHOD FOR DETERMINATION OF THE HEIGHT OF EMBANKMENTS ON ICED-OVER PORTIONS OF THE CENTRAL TRANS-BAIKAL

In the USSR there has been accumulated and correlated much experience in the struggle to control ice layers of varied origins. The article proposes methods for determining the height of embankments of rail and automobile roads on sections with ice formation in the Trans-Baikal region. The analysis of the layout of 370 km. of automobile roads built with various types of road surfacings and the research on ice formation in 1964-1970 established that the height of road embankments on sections in the Central Trans-Baikal is determined by the maximum strength of the ice layers. Observations revealed that the greater the volume of ice layers and the gradient of the ice-formation section, the greater the strength of the ice forming in the road. The form of the ice and its geometric dimensions are stipulated by the form of the river valley. In a wide valley the ice has the possibility of spreading over a large area and therefore its average strength is small, whereas in narrow valleys the strength of the ice is significantly greater. According to the proposed nomogram it is possible to define the height of the ice, by allowing the exclusion of the escape of ice layers onto the roadbed, and, consequently, the shortening of the road construction period and the decrease of stability due to the elimination of changes which bring the height of the ice up to the required mark during the course of operations.
