Quick method of the grunt prisms gravity centers’ exact compliance with vertical area planning

Abstract

The article discusses the methods for improving the accuracy of calculating the soil movement distances along the vertical layout of areas, which is one of the first works for leveling the construction site surface [3, 5, 6, 14]. This work is usually performed using the earth-moving machines [12, 17, 19, 20]. Norms of time for their work are given in Unified Standards and Prices E2-1 [13] with gradation of the soil movement distances of 100 and 10 m. When vertical planning is required on the large areas with the soil movement over the distances of several hundred meters and with large working elevations, the options for using faster motor vehicles are possible [1, 2, 10, 11]. However, not all standards indicate between which points and how to set these distances. We believe that it is advisable to install them using the positions of the soil bodies’ gravity centers instead of the commonly used the centers’ positions of their areas [9, 18]. This will increase the reliability level of the soil movement distance to establish the appropriate costs of computer time [7, 8]. The formulas for determining the positions of the gravity centers of bodies (BGC) are given in the reference book [9] and in other sources.
