Method for Compaction Control of Artificial Foundations with Coarse Clastic Soils

The developed method is intended for operational control of the compaction of artificial foundations built in layers during large volumes of work. The method makes it possible to determine the coefficient of compaction of the base (ky), composed of coarse-grained soils with a fraction that exceeds the limits established by regulatory methods. The compaction factor was determined as a result of special studies, taking into account the corresponding increase in the scale of field and laboratory work. Additionally, the values of the compaction coefficient ky of the base are made dependent on the readings of the dynamic density meter, recorded at the same construction site, which makes it possible to significantly speed up and reduce the laboriousness of the work on monitoring the compaction of the bases. The dependence proposed in the work allows you to quickly control the compaction of an artificial foundation by performing the required number of measurements with a dynamic density meter. The paper also solves the practical problem of determining the relationship between the number of penetrations of a vibratory roller of a given model used on a construction site along the compacted soil layer and the compaction coefficient ky. The resulting dependence allows you to set the time and intensity of the work of equipment in the area of the compacted base in order to increase the effectiveness of the subsequent main control measures.
