本文介绍了在波兰西北部的安托尼特试验场,在有机土壤上进行的两阶段建造试验路堤的土壤调查、施工以及预测和观测结果。这两个试验堤坝建在8米厚的非常软的有机和石灰性土壤之上。路堤已分阶段修建,不同阶段固结所增加的抗剪强度已成功地用于后续阶段的施工。其中一个堤坝下安装了垂直预制排水沟。在建造堤坝之前,进行了一项全面的现场和实验室试验方案。堤防内外的地下也安装了大量的监控设备。观测了路堤在沉降、水平位移和孔压方面的行为,并测量了土性的变化。这些行为和性质的变化已经与使用各种预测方法的预测进行了比较。对加固时剪切强度的提高和预制排水沟在恶劣环境条件下的耐久性进行了特别调查。
This report describes the results from the soils investigations, the construction and the predicted and observed behaviour of two stage constructed test embankments on organic soil at the antoniny test site in north western poland. The two test embankments have been built on top of 8 metres of very soft organic and calcareous soils. The embankments have been built in stages and the increase in shear strength due to consolidation in the different stages has successfully been utilized in the construction of the subsequent stages. Vertical prefabricated drains were installed under one of the embankments. A comprehensive programme of field and laboratory test was carried out before the construction of the embankments. A large amount of monitoring equipment was also installed in the ground under and outside the embankments. The behaviour of the embankments in terms of settlements, horizontal displacements and pore pressures has been followed and the changes in soil properties have been measured. The behaviour and the changes in properties have been compared to predictions using various methods of prediction. Special investigations have been carried out concerning the increase in shear strength at consolidation and the durability of prefabricated drains in harsh environmental conditions.
