Abstract

A low test embankment have been constructed on a soft and fibrous peat deposits. The thickness of the soft peat layer is about 2.5 m. Under the peat layer, there is silty clay deposit with thickness of about 13m. The site investigations were performed for both the layers. The laboratory soil tests on undisturbed samples obtained from both the layers were carried out. The settlement of foundation deposits was predicted by the one dimensional consolidation theory using the soil parameters obtained from laboratory soil tests. The results of field observations were compared with the calculated results by the conventional theory. The results of observations and calculation do not agree. If the settlement of foundation deposits under embankment loading is predicted by a monitoring method, it appears that a lot of case records of settlement give the conclusion that the agreement of the prediction and the field observation is favourable.

Settlement Measurements of Peat Deposits as Embankment Foundation

A low test embankment have been constructed on a soft and fibrous peat deposits. The thickness of the soft peat layer is about 2.5 m. Under the peat layer, there is silty clay deposit with thickness of about 13m. The site investigations were performed for both the layers. The laboratory soil tests on undisturbed samples obtained from both the layers were carried out. The settlement of foundation deposits was predicted by the one dimensional consolidation theory using the soil parameters obtained from laboratory soil tests. The results of field observations were compared with the calculated results by the conventional theory. The results of observations and calculation do not agree. If the settlement of foundation deposits under embankment loading is predicted by a monitoring method, it appears that a lot of case records of settlement give the conclusion that the agreement of the prediction and the field observation is favourable.
