To assess the stress-strain state of the reinforcing layer, it is necessary to directly measure stresses in geosynthetic interlayers. When measuring the stress-strain state of structures and materials, the tensometric method is often referred to. The current strain gages have a lower maximum elongation than the elongation occurring in the geosynthetic interlayer, therefore, there is a need to develop an appropriate load cell. In this paper, a constructive scheme of a tensometric sensor designed to measure deformation in geosynthetic material under tensile stresses is selected, its calculation is carried out in alphabetic form, internal forces arising from stretching of geotextile are revealed, the formula for the dependence of the relative elongation on the geometric parameters of the sensor is derived. An analysis is made of the influence of geometric characteristics on the immediate dimensions of the structure.
