Geotechnics | Free Full-Text | Investigating Sand Production …
Sand production is independent of hole size in low stress conditions and weak rocks. In other words, with respect to low strength rocks at low stress conditions, the process of sand production is less sensitive to hole size. This is an important factor to consider in deciding the dimensions of test specimens. A big specimen is generally preferred.
