SOFT SUBSOIL EXPLORATION AT THE KOISE RIVER VALLEY ON THE JOBAN LINE--COMPARISON OF EFFECT OF TREATMENTS FOR SOFT SUBSOILS

According to the subsurface investigations, the Koise river valley consists of a very soft upper peat layer and also of very weak lower marine clay strata, the total depth amounting to 20 meters. When the subsurface conditions are unfavorable like here, several treatment methods for weak subsoils have so far been adopted so as to make the newly constructed embankments stable, though the effectiveness of the method is a great problem. Therefore, in order to ascertain the relative effectiveness of each treatment method, the experimental embankment was planned and for the purpose the present site where the subsoil conditions are most unsuitable was chosen. The experimental embankment consists of three sections, "Composer" "Cardboard Drain" and non-treated, and the effectiveness of the two stabilization methods was evaluated by comparing directly the measured data with those of non-treated.
