agriculture and construction engineering. SUBSTANCE: method involves throwing load along guiding bar onto shock-absorbing device to provide deformation of ground layer through die, with load being changed according to law close to trapezoidal; detecting longitudinal lambda11 and transverse lambda22 of ground layer deformation, which are developed in time, by means of deformation sensor and rocker arm; detecting maximal deformation Hcomp of shock-absorbing device by means of maximal deformation indicator; determining on the basis of resultant data parameters of longitudinal and transverse creep test curves and instant longitudinal modulus of ground layer deformation and function of shear and volume creep rates. EFFECT: increased efficiency, provision for precise measurements and wider information content of obtained results. 3 cl, 3 dwg |
