Аннотация

The method of soil compaction with heavy rammers was proposed by Professor Abelev Yu.M. in 1948. Later this method under the name “Russian rammers” was applied in France (since 1953), and later in other countries. However, despite the widespread application of this method, there are still no methods for calculating soil compaction of various origins with certain strength and deformation characteristics. The developed methodology of nonlinear calculation of the foundation during compaction with heavy rammers is presented. For this purpose numerical calculation methods using explicit schemes of equation systems integration are applied to modeling of nonlinear compaction processes.
