Abstract

The discussion on the title paper is focused on following points:
1. As for the proposed first evaluation method, an essential term is omitted which becomes important for the case of deeply embedded foundation and for higher frequency.
2. The range of applicability of the first method should be stated clearly not so as to be misused.
3. The second proposed method seems to require more numerical calculation step than the existing evaluation method proposed by Iguchi³⁾, and Kurimoto and Iguchi⁴⁾.
