In the west of Osaka city, a number of canals for woods were filled up with earth. On this reclaimed land, many buildings were constructed. Settlements were observed at one of these buildings and 12 ground points around this building. The observed building has 11 stories and the plan 3spans×32spans, whose structure was constructed with reinforced concrete and supported on sandy diluvium. In this paper, results of observed settlements are shown and observed settlements are compared with calculated settlements by equations which introduced in previous paper (part 1). Main conclusions are as follows. 1. A shape of a building settlements were influenced evidently not only loads of a building itself but also loads of earth around a building. 2. Observed settlements are slightly larger than calculated settlements in diluvium. But these twe kinds of settlemnts agree fairly in alluvium. 3. Such as this case that loads of earth and loads of the building overlap, it is effective to use the theory that the coefficient of volume compressibility m_υ and the coefficient of consolidation c_υ are treated to be variables.
