METHOD OF DETERMINING BEARING CAPACITY OF GEOTECHNOGENIC SYSTEMS Russian patent published in 1999 - IPC

FIELD: construction; applicable in determination of bearing capacity of artificial bases (geotechnogenic systems) made by injection into ground of consolidating solutions (mortars) and chemicals. SUBSTANCE: taking into consideration the complexity of evaluation of bearing capacity of geosystem for time of transmission of calculated loads from structure, subjects to measurement and determination are space position, sizes and strength of separate members of ground mass in different intervals of time after injection of consolidating materials into ground, for instance, in 1 - 7-10 days, and dependence of measured parameters and their variation on time. Obtained dependence make it possible to determine bearing capacity of separate members of geotechnogenic system corresponding to preset time, and total data on obtained results allow determination of bearing capacity of geosystem as a whose on the basis of respective programs of engineering computations. Method of measurement may be used in the form of static or dynamic sounding, geophysical methods and others, and dependence of measured parameters on time is offered to be presented in the form of logarithm function. EFFECT: higher reliability in determination of bearing capacity of geosystems. 6 cl, 3 dwg
