Theoretical Researches of Rammer's Operating Element Dynamics in a Soil Foundation of Oil and Oil Products Storage Tank

The development of technologies for a directional soil compaction is a new prospective task which solving will enable to obtain the required carrying capacity of soil foundations with a rational use of construction materials and to provide a trouble-free operation of engineering structures. Theoretical researches were carried out to study characteristics of physical and mechanical processes of an impact action for rammers operating elements on foundation soils for oil and oil products storage tanks. In the course of the conducted analytical studies of the dynamics for a conic model impact action on a dispersed noncohesive soil we obtained the dependence of the model's motion velocity change on impact parameters. The increase of the model impact velocity from 0.47 to 1.40 m/s resulted in the reduction of interaction process duration in a «model-soil» system from 90 to 56 ms.
