They were trimmed and placed in a 6cm\u00d72cm oedometer. The specimen was loaded under incremental load in the compression test. In the soaking test the specimen was soaked under various constant loads. The amount of compression of the compacted sample on the dry-side of optimum water content is smaller than that of the compacted sample on the wet-side. The compression of compacted partly saturated soil is divided into three parts, namely : instant compression, primary compression and secondary compression. The compression of compacted sample on the dry-side is mainly due to the instant and secondary compression. On the other hand, the compression on the wet-side is due to the primary compression. The compacted sample on the dry-side is much affected by soaking under constant load, but the effect is less on the wet-side.

| 内容記述 | 沖縄本島の2種類の粘土について, 締固め不飽和粘土供試体を成型し, 側方拘束一軸方向への圧縮および吸水変化について実験を行なった。本実験から言えることは1)最適含水比およびそれより乾燥側で締めた方が湿潤側で締固めるより圧縮量は少ない。2)最適含水比より湿潤側で締固めた状態の圧縮量は初期圧縮と二次圧縮に依存し, 粘弾性の効果が大きい。一方, 最適含水比より湿潤側での締固め状態の圧縮量は飽和粘土の圧密曲線に類した一次圧縮の影響が大きい。3)締固めた粘性土の水に対する安定性は最適含水比およびそれより乾燥側で締固めたものより, 湿潤側で締固めた方がよい。 | |||||||||
