Case Study of Modulus of Deformation of Railway Earthworks by Static Plate Load Test
Publication: Tran-SET 2022
ABSTRACT
Railway earthworks provide a static platform for the track substructure. When constructing any railway structure with codified design resistance, earthwork layers of certain thicknesses and modulus of deformation need to be installed. The main objective of this study is to evaluate the deformation and strength characteristics of embankment soil by using the load-settlement curves. In this research, the Static Plate Loading Test, as per Indian Standard (IS) 1888, has been followed to obtain the stain modulus (Ev) of earthworks. An effort has been made by the researcher to utilize the railway earthworks including embankment, subgrade, and sub-ballast layers, which are categorized as sand and gravelly soil, sandy soil, and composite materials, respectively. The EV2 values of these layers are found to be 71.2, 119.6, and 183.1 MN/m2, respectively. The outcomes of this study are expected to help construction engineers in regulating the compaction quality for railway earthworks.
