ASSESSMENT OF THE QUALITY OF FORMATION DURING EARTHWORKS

The paper examines the influence of deviations in geometric parameters during excavation work and terrain conditions on the accuracy of determining the cross-sectional area in road construction. A detailed examination of the accuracy of the processes that determine the quality of shaping during excavation work in all their diversity is substantiated. Possible approaches to assessing the quality of shaping of objects are considered. It is proposed to use construction tolerances as limit deviations to assess the magnitude of deviations in the planned and altitude position of cross-sectional points of the roadbed. It is shown that the steepness of the slope and working marks can significantly affect the relative changes in the cross-sectional area. It is necessary to take into account the conditions of work at all intermediate stages. The obtained dependencies for determining the relative changes in the cross-sectional area take into account the influence of the working mark, slope steepness and hill slope. They can be used to standardize the requirements for the quality of shaping and initial information when designing slopes in different conditions, including when designing the roadbed of highways.
