繰り返し荷重による土層の永久沈下に関する考察(時間要素を考慮した場合)  [in Japanese] On the Permanent Depressions of Soils under Static Repeated Loading considering the Time Factor  [in Japanese]

On the permanent depressions of soils under static repeated loading, the time factor is almost negligible when the soil is composed of granular materials, but we can easily expect the time factor when the soil contains clay. In this paper we studied the permanent depressions under static repeated loading considering the time factor and introduced the following formula;where, [numerical formula] (1) [numerical formula] (2) [numerical formula] (3) E_1,η_1 are shown in Fig . 1. We applied the formula in Seed and Chan's experimental results and calculated the charac-terristic coefficients A, B, α and added some considerations
