内容記述(抄録等)
The oedometer tests and triaxial compression tests were performed for the soft reclaimed clay of Hikona area. From these tests, the consolidation yielding stress P_y of the clay about 30cm depth is about 0.07-0.12kgf/<cm>^^^2 and this value is about 2.5 times of the overburden pressure. The coefficient of consolidation c_v from √<t> method is larger than that from log t method and c_v calculated from the settlement data of the field is the largest. The shearing properties of the clay is similar to that of remouled clays.
The process of drying of the surface were carried out a suryey with cone penetration tests and sampling of soils. The moisture content of surface soil about 30cm is decreased by the drying for four years but the moiture content of soils deeper than 30cm are affected by the drainage of surface water and groundwater. The cone bearing capacity is increased gradually for four years but the trafficability for the bulldozer for super swamp is not obtained in the part of soft clay layer. The drainage ditches for the surface water and groundwater are necessary for the more drying of the reclaimed clay layer.
