学术报告摘要：
Two documented case histories involving geosynthetics stabilized embankments on soft soils are discussed with particular emphasis on predicting their performance and design implications. A polyester woven geotextile was used as reinforcement for the test embankment constructed at Sackville, New Brunswick, Canada and its short term performance was investigated. Predictability of the behaviour of Sackville embankment under working stress conditions was investigated using the FEM with three different models, namely Modified Cam Clay (MCC), a rate based elasto viscoplastic and a creep based elasto viscoplastic model, to represent the foundation soft soil. This study suggests that all three models are capable of predicting the performance of this embankment satisfactorily despite their inability to give accurate predictions of all the behaviour characteristics for the entire construction. A geogrid reinforced embankment was constructed on a PVD stabilised soft soil adjoining an existing road at Leneghans, NSW, Australia and its performance was monitored over a long period. This embankment was analysed with MCC and creep model and the creep model was found to predict the multiple characteristics better than the MCC model. The combination of field data and numerical analysis are used to provide insights regarding factors to be considered in future design and for predicting the performance.
