井口道雄氏の討論に対する回答

抄録

The authors would like to thank Prof. Michio Iguchi for his discussion, and the answers are as follows;
(1) We corrected the sign of Φ_y^* in the section 1 of equation (2). And also we corrected the description of related equations (3), (7), (15) - (18).
(2) We think the first evaluation method is useful as an approximate solution, though it is improved by considering the excavation force.
(3) We proposed that the first evaluation method should be used when the ratio of embedded depth and half foundation width is smaller than 3.0.
(4) About the numerical calculation step of the second evaluation method, we think it is a difference in approach about how to lead from the exact solution to a convenient solution.
