This report presents an experimental method for predicting instant, transient and creep settlement of direct foundations on Kanto Loam. The applicability of this method was also examined by comparing actual and predicted foundation settlements. Special attention should be given to the following Conclusions. (1) Instant settlement can be predicted using elastic theory when Young's elastic modulus, E is assumed equal to 145 qu. (2) The relation between transient settlement, S_<EC>, and time, t, is a straigth line on the S_<EC>-log t plane, with the settlement rate being in inverse proportion to E. The same has also been observed in regard to the behavior of creep settlement, S_c, time in logarithm, log t, and E. (3) As a general rule '. total settlement of an ordinary continuous footing on Kanto Loam is about 0. 36 cm to 2. 72 cm over a period of 10 years, while creep settlement is in the range of 30 to 60% of the total settlement and averages 50%. Transient settlement included in the total settlement is negligible.
