True-Triaxial Drained Test of Tengger Desert Sand

Loading schemes with different b.

b	Time (min)	Effective confining pressure (kPa)	Loading scheme
0	240	100	Two rigid loading plates and a flexible loading plane were used in the test. After isotropic consolidation, according to the definition of bε in equation (2) and controlled by bε = dε2/dε1, ε1 and ε2 were set, and the confining pressure was kept constant; that is, the load of equal b was realized
