METHOD FOR DETERMINING GRAVITY PRESSURE AND COEFFICIENTS OF GENERAL LATERAL PRESSURE AND GENERAL RELATIVE LATERAL DISTORTION OF SOIL AND PEAT GROUND

摘要

FIELD: physics.SUBSTANCE: invention refers to physics of material contact interaction of a both natural, and damaged ponderable medium in mass and at a crest of slopes. The parameters of an angle of internal friction ?and a specific cohesion ?of the sampled medium taken at a depth h of the ponderable material mass are determined in the laboratory environment. The dependences ?=arcsin[2sin?/(1+sin?)]- ?, c=c[2-tg?/tg?] are used to derive the parameters of an angle of internal friction and a specific cohesion of the structurally damaged medium at a survey depth respectively, wherein p=(?h-c)ctg?is a natural pressure at the depth h. A tangential natural pressure at the depth h is defined as ?=p=p=?h·cos?. The dependence derived by the author is used to determine the parameters of a coefficient of general lateral pressure of the medium at restat damaged natural mass structurein open pit wallsand in open pit walls with damaged structureCoefficients of general relative lateral distortion of the medium mass are determined according to the dependence derived by the authorrespectively,in side walls of an open pit,wherein p=1.033 kg/cmis a normal atmospheric pressure on the material medium,is a specific gravity of the damaged medium.EFFECT: more informative and reliable determination is achieved.3 cl, 3 ex, 2 dwg
