Have there been triaxial tests done on soil, where the conventional external confining pressure would be substituted by internal vacuum?

This could lead to greatly simplifying the equipment, cheap soil curing methods (already used in practice, some of them are), and increase reliability together with decreased labor demand on large scale tests in the laboratory.

Dear Tomas

The idea is new. Whilst making the specimen (sand) a small vacuum pressure is kept until the confining pressure is applied.

However, I wonder how to measure the pore pressure during the test.
