For an ongoing research project, I am delving into measuring air pressure and possibly the volume of trapped air within soil specimens during triaxial tests for unsaturated soils. The intent is to gain a more comprehensive understanding of the role and behavior of trapped air in the context of unsaturated soil mechanics.
I would appreciate any references or insights from anyone who knows of past research, published studies, or even ongoing unpublished studies related to this topic. These can provide a foundational understanding and possibly guide the direction of my experiments.
While I am in the preliminary stages of my experiment and have specific methodologies in mind, it would be invaluable to learn from the experiences of those who have traversed this path before or are currently exploring similar avenues.
Thank you in advance for your assistance and expertise!
