This report presents the system and the more economical design method of the program for the automatic design system. This is developed for the unsysmmetrical bar arrangement of the caisson being used as quay-walls or breakwaters adding these new method as follows; 　1. the new alternate arrangement of the horizontal reinforcement of 10 or 20cm pitch on the partition wall. 　2. another calculation considering 1/3 haunch thickness as the effective pressure on the materials with haunch. 　The comparison of the results between the revised one and existing program is also presented to clarify the effects of the new method.
