METHOD OF CARRYING CAPACITY DIAGNOSTICS OF SOILS OF TECHNICAL SYSTEM Russian patent published in 2009 - IPC G01N33/24 

FIELD: physics, measuring.

SUBSTANCE: invention concerns building, and in particular to field of building new and operation of old soil technical systems "road bed - basis" at action of adverse factors: technogenic static, nature-climatic, vibro-dynamic, eigentones TS etc. The method of technical system soil carrying capacity diagnostics (TS) includes installation of the basic pair of data units for measuring pore-pressure and temperature of a vapour-liquid phase of soils in pre-bottom band of the basis of TS the, measuring pore-pressure , and temperature , before and after application of an inertial reaction and determination of differences of measured parametres on which judge a carrying capacity of soils. In a direction of probable display of strains of the TS mount an additional pair of data units for measuring of pore-pressure and temperature in which measure pore-pressure , and temperature , of a vapour-liquid phase of soils before and after the inertial reaction application. Determine differences of parametres of the second point of measuring before and after the inertial reaction application and estimate carrying capacity of soils in addition under the relation of differences δP² / δP¹, δT² / δT¹: at δP¹ ≈ δP² ≈ 0, δT¹ ≈ δT² ≈ 0 and δP² / δP¹ = 0, δT² / δT¹ = 0 do a deduction about a stable state of soils of the TS, at δP¹>0, δP²=0, δT²>0, δT¹=0 and δP²/δP¹=0, δT²/δP¹ to =0 initial losses of a carrying capacity of soils of the TS, at δP²<δP¹>0, δP²/δP¹<1 and δT²<δT¹>O, δT²/δT¹<1 - about a feeble carrying capacity of soils, at δP²≈δP¹>>0, δT²/δT¹>>0, and δP²/δP¹≈1, δT²/δT¹≈1-o to losses of carrying capacity of soils of the TS.

EFFECT: increase of reliability of determination of TS soil carrying capacity state.
