Stress Path Triaxial (GDSTTS) with Temperature Control
The stress path test is commonly used to simulate the changing mechanical properties of soils, whilst under varying stresses. Research in this area, within China and abroad has gradually increased. The static triaxial apparatus based on the Bishop Wesley principle is widely accepted. However, in reality, the stress change of soil is usually accompanied by changes in the environment.
These environmental factors include changes in humidity, temperature and chemical invasion. Temperature change is the most common factor, in certain conditions the temperature changes can vary tens of degrees. Such variations are often accompanied by stress. What impact will this have on the mechanical properties of the soil? Will there be any difference when doing the same test on different soils? These are problems that Mr Wang from Nanjing Forestry University was investigating.
