An Investigation into the Influence of Sample Height on the Consolidation Behaviour of Dredged Silt

This study delves into the effects of sample height on consolidation behaviour, utilising automatic air pressure consolidometer. Extensive tests were conducted three varieties dredged silt samples varying heights from Qianwan, Shenzhen, China. The salient findings can be summarised as follows: (1) Compression curves for different dimensions transitioned through distinct phases: minimal load disturbance, elastic deformation, and plastic deformation. Notably, void ratio during latter two phases diminished increased. (2) A rising corresponded to a reduced stable strain compression index. Furthermore, coefficient notably with an escalation in height, whereas structural yield stress remained largely unaffected. (3) Given disparate formation processes, histories, material compositions between marine silts, permeability was found superior that silt. Within typical preloading scope (50~300 kPa), lower compared However, significantly surpassed this threshold, disparity silts narrowed.
