ABSTRACT
The framework of soil mechanics (geomechanics) was established by Karl Terzaghi (Terzaghi 1943), and two famous English textbooks of soil mechanics (Terzaghi and Peck 1948; Taylor 1948) were published in 1948. Later, soil mechanics from that time was named the “1948 model of soil mechanics” by my supervisor, Toru Shibata (coincidentally, 1948 is my birth year). Practical designs of most geotechnical problems have been done more or less based on the ideas of these books.
