Doctoral student: Muhammad A. Zardari Supervisors: Prof. Sven Knutsson and Dr. Hans Mattsson, Department of Civil, Environmental and Natural Resources Engineering

Start date: November 2008
Expected completion date: December 2012

Funding: (i) Quaid-e-Awam University of Engineering Science and Technology, Nawabshah, Pakistan for financial support to the doctoral student, (ii) Luleå University of Technology, Luleå, Sweden for research related costs.

Aim: To assess the stability of tailings dams during staged construction and the long term (i.e. 1000 years) using finite element method. The focus of the project is to: (i) properly understand the mechanical behaviour of the tailings material,
(ii) check the suitability of available soil constitutive models for the tailings material,
(iii) perform numerical analyses of tailings dams with suitable constitutive models, and
(iv) formulate criteria for assessment of long term stability of tailings dams based on the results of the numerical analyses.

Progress: Licentiate Thesis titled Stability of Tailings Dams: Focus on Numerical Modelling
