METHOD FOR DETERMINING THE VALUE AND DIRECTION OF DEFORMATION OF THE OUTER COMPONENT OF THE FROST BLISTER OF PERMAFROST

摘要

FIELD: monitoring systems.;SUBSTANCE: invention relates to geodetic spatial monitoring of engineering structures and natural objects and can be used both for observation of sediments and deformations of engineering structures, and natural objects (hillocks, dips, hills, slopes, landslides, etc.). Claimed method for determination of value and direction of deformation of external component of frost blister of permafrost, including creation of plan-altitude justification, fixation of points along perimeter of frost blister, performance of geodetic measurements. According to the invention, the above points along the perimeter of the frost blister are arranged and rigidly fixed on the sides of the light north, west, south, east, drilling of the wells located on the top of the frost blister, the sole of the frost blister. Fixed boundary points are used to define an approximate boundary of an underground constituent of a heaving mound; drilling is performed until determining accurate boundaries of the underground component of the frost blister. Determining coordinates of X, Y, Z of all fixed points and drilled wells is performed by lowering the thermoset to drilled wells and performing temperature measurement. Obtained digital information is transmitted to a computer program, and a digital hummock model is constructed. B same program, the model of an external contour of the frost blister is combined with a model based on the results of previous measurements of the outer outline of the frost blister of permafrost. In automatic mode, value of deformation and direction of external component of frost blister of permafrost is determined.;EFFECT: high accuracy and reliability of determining the value and direction of deformations of the outer component of frost blister of permafrost.;1 cl, 4 dwg
