JGS Standards

In 2014, the Japanese Geotechnical Society (JGS) began the task of translating its standards (Laboratory Testing Standards for Geomaterials and Geotechnical and Geoenvironmental Investigation Methods) into English. The English language standards issued in sequence in three volumes (vol. 1-vol.3).

We hope the English language versions of Japanese Geotechnical Society Standards will be widely used in the many countries that have ground conditions similar to those in Japan, for ground investigation, design, construction, training of geotechnical engineers and so on.
