Stress determination in soils from variation in level of infrared radiation during unloading

Sheinin, V. I. / Morozov, A. A. / Motovilov, É. A. / Filippova, S. V.

Abstract A procedure for and results of model experiments conducted on insulated soil specimens in connection with the development of a method of measuring stresses in soil masses in accordance with an “unloading” scheme using infrared radiometry are discussed. The principal feasibility of the complete unloading of a volume of a slightly cohesive soil without its “instantaneous” failure with simultaneous thermoradiation measurements is indicated. A linear relationship is established between the change in the intensity of the radiation flux during unloading and the contact stress on the boundary of the specimen, which simulates the level of stresses in the mass. The value of the coefficient linking the indicated values can be used to interpret IR measurements conducted in other tests of the type of soil in question, including in-situ tests.
