Particle Morphology of Geotechnics. The Influence Of Particle Morphology Of Granular Soils On The Relationships With Shear Strength And Dilatancy Behaviour

      Аннотация: This book describes the key factors of particle morphology quantification and its characteristics that govern the interparticle behaviour of granular soils. A standardised and cost effective method of quantifying particle shape parameters has not been widely recognised yet, therefore the methods are still being debated today. In this booklet, explanation of a new approach of particle shape classification was presented. Cluster and statistical analysis was used to find a single representative value of the particle shape parameters from 5 different sand samples. With that, the behaviour of the shear strength and dilatancy parameters of granular soils was able to be understood clearly. Thus, this contributes in improving the fundamental understanding on the development of parametric correlations on the strength behaviour of sands based on the new methods of particle morphology classification.
