Introduction in the theory of involvement of soil masses in movement with specific reference to the soil processing

Imamov I.S., Belov S.V., Vorobiov Y.I.


Technologies of mechanical soil tillage assume its deformation and destruction. These processes are difficult for generalization and mathematical description. Basic provisions for determination of wave grounds of energy transfer in soil body during its deformation and destruction are proposed. A way to clarify the rational equation of academician Goryachkin V.P. concerning the traction resistance of tillage tools based on the principles of theory of involvement of soil masses in movement are suggested.

Influence of absolute soil humidity on the porosity of soil packing

Makhmutov M.M., Chepurnoy A.I., Makhmutov M.M., Dzhabarov A.K.


The influence of absolute soil humidity on the porosity of soil packing is shown. It is noted that soil porosity will be reduced at the expense of decreasing of air pores and increasing of solid particles volume as a result of soil compression with mover, strake, block etc. at constant humidity. The analysis of obtained models is given.
