Determination of the snow cover weight and altitude coefficient values in mountainous and poorly studied areas for assessing loads on buildings and structures

Abstract

The materials use in structures and calculations for buildings and structures in Russia is determined, inter alia, by the normative loads of snow cover on the construction site. An urgent task is to determine its significance for the unexplored areas. The results of determining the normative value of the snow cover weight and changes with the height of the snow weight terrain for the designed objects of the “Udokan” Mining and Metallurgical Combine at the altitudes from 600 to 2000 m are presented. To determine the estimated snow load on buildings and structures in the territory of the facility creation, we used the series of the water supply annual maximums in the snow cover obtained as a result of the snow-measuring route observations at high-altitude weather stations located close to the designed objects. Based on the data of weather stations, a regression linear model of the water supply dependence in the snow cover on the height above the sea level was built. The main calculation method for finding the coefficients of a linear equation is the least squares method. It was revealed that with an increase in the height above the sea level by 1 m, the water supply in the snow cover increases by about 0.1 mm.
