KHRUSTALEV METHOD OF DETERMINING MECHANICAL PARAMETERS OF MATERIAL MEDIUM IN MASS Russian patent published in 2016 - IPC G01N3/14 

FIELD: physics.

SUBSTANCE: invention relates to "Physics of material contact interaction" of ponderable medium in its mass and at edges of slopes in natural and disturbed state. At depth h in ponderable material mass, determining on collected samples of medium in laboratory conditions parameters angle φ_str internal friction, c_str - specific adhesion and γ_str - specific weight of medium. Calculating based on relationships $${\gamma }_h=\frac{p_{b}tg{\phi }_h+c_h}{h}$$ - respectively parameters for internal friction, specific adhesion and specific weight of medium at depth of testing in structurally disturbed state, where p_b=(γ_strh-c_str)ctgφ_str - natural pressure at depth h. Determining value of tangential natural pressure at depth h as p_x=p_y=γ_strh or p_x=p_y=γ_h(h). Determining parameters of coefficient of total lateral pressure of medium at rest $${\zeta }_0^{str}=tg{\phi }_{str},$$ at failure of natural structure of mass $${\zeta }_0^h=tg{\phi }_h,$$ in walls of open basin and in walls of an open basin with a deformed structure Coefficients of total relative transverse deformation of medium in mass are respectively defined by relationship and side walls of open basin, where p_atm=1.033 kg/cm² - normal atmospheric pressure on material medium $${\gamma }_h=\frac{p_{b}tg{\phi }_h+c_h}{h}$$ - specific weight of medium with a deformed structure.

EFFECT: increased reliability and accuracy of determining physical parameters of soils.
