Underground Space Construction by Explosive Loading in a Borehole Kazuyoshi Tateyama1, a , Shigeru Itoh2,b and Hironori Maehara3,c 1 College of Science and Engineering, Ritsumeikan University, Kusatsu, Shiga 525-8577, Japan 2 Shock Wave and Condensed Matter Research Center, Kumamoto University, Kumamoto 860-8555, Japan 3 Shock Wave and Condensed Matter Research Center, Kumamoto University, Kumamoto 860-8555, Japan a tateyama@se.ritsumei.ac.jp, b itoh@mech.kumamoto-u.ac.jp c maehara@shock.smrc.kumamoto-u.ac.jp, Key Words: shock wave, soil compression, underground space, experiments, numerical simulation Abstract: In cases where a borehole has been dug in the ground and subjected to an explosive load, the soil around the borehole wall will be abruptly compressed and a cavity will then be created in the portion of the ground that is surrounded by the compressed soil wall.
This means that the rod, compressed by the impact load, includes a section where the material is compressed in concentration.
