Investigation of ground and foundation vibrations of an existing building during impact pile driving
Abstract Pile driving technology remains the most common in Arkhangelsk where the presence of soft soils is an engineering-geological feature. New construction is mainly carried out in the conditions of existing urban development. During pile driving dynamic effects that propagate in the ground can...

Abstract Pile driving technology remains the most common in Arkhangelsk where the presence of soft soils is an engineering-geological feature.
