dc.descriptionThis is an accepted manuscript of an article published by Elsevier in Engineering Geology on 21/10/2016, available online: https://doi.org/10.1016/j.enggeo.2016.10.009 The accepted version of the publication may differ from the final published version.
dc.description.abstractPeat is a very variable but normally weak material. While engineering failures involving peat are common, the full diversity of engineering behaviours exhibited by peat has not been well classified due to its large range of possible compositions. This paper presents the behaviour of a fibrous peat which is a fill (made ground) originating from the most recent dredging of the West Lake, a site of cultural and historic importance in China. Given its relatively unique mechanism of deposition, the distinctive characteristics of this peat are presented in comparison to other peats reported in the literature highlighting its unique engineering behaviour. A laboratory study carried out on the peat at Jiangyangfan Eco-park, located in Hangzhou, China identifies that it has its special aspects when compared to other peats. The shearing behaviour of peat can be described using the framework of critical state theory. The most prominent characteristic of the West Lake Peat is that its undrained stress path bends towards the left at the very beginning of shearing which indicates that plastic deformation occurs at very small stress ratios. A constitutive model based on critical state theory for predicting the undrained shear behaviour of this type of peat from low stress to critical state levels is presented. This model also includes several elements of peat behaviour previously reported and it may therefore be applied to a wider range of peat soils.
