2. Soil resistance to liquefaction

2.1 Cyclic soil behavior

In the laboratory, the cyclic behavior of soils is studied using various types of mechanical test, each covering part of the range of shear deformations between 10 ^–6 and 10 ^–2 .

Figure 3 shows an example of shear stress-strain curves obtained with the cyclic triaxial apparatus in eight successive sequences of fifty cycles and amplitudes ranging from 7.10 ^–5 to 2.10 ^–2...
