Permeability evaluation method of ground material using a test piece that reproduces ground material

摘要

PROBLEM TO BE SOLVED: To increase the convenience in performing a permeability test on a ground material.SOLUTION: A test piece reproducing a ground material is formed by a 3D printer, and various types of permeability tests are performed using the test piece. If a clogging has occurred in the test piece due to salt water used for the permeability tests, the tests can be re-started using a new test piece. Also, forming the test piece of a transparent or semi-transparent material is preferable in that an inside fluid behavior can be seen.SELECTED DRAWING: Figure 1
