What is it about?
The article introduces a new device for measuring cohesive and adhesive resistance in soils. The device allows for simultaneous measurement of cohesion and adhesion on a single specimen, and determination of adhesion factor for soils.

Why is it important?
Article emphasizes the importance of considering both cohesive and adhesive stresses, lower deformation levels, and accurately simulating actual drainage boundary conditions when estimating adhesion factors, particularly in applications such as shield tunneling.
Perspectives
I hope the readers find the work to be interesting, and the device to be an interesting and simple way to determine the adhesion factor of soils.
