Studies of Tixotropic Changes in Clay Soils Can Also Be Carried Out in Stabilometers, Odometers and Shifts. In them, you can simulate the Process of Tixotropic Hardening by Creating An Appropriat Stress State in the Ground, Which Will Take Place in the Conditions. The Best Devices for Determining the Strength Characteristics of Soils Are Stabilometers that Have Significantly Wider Capabilites for Modeling Real Conditions of Their Operation, Sinse Thhees Devices You can artificelly Create Any Ratios Between the Main Stresses and TheFore Use for the Quentitive Characteristics of Tixotropic Hardening In soils.
