Effect of subsidence on structures built over old mining works in french iron basin

Abstract : All mining works can generate strata movements and lead sometimes to serious consequences to structures. This paper presents an original analysis of mining subsidence effects on surface structures. We present in the first part of this paper the results of a numerical model, which allows a global understanding of the structure cracking process. A real subsidence profile was applied at the bottom boundary of a finite element model and soil-structure interaction was studied by introducing a simplified structure at the top of the numerical model. A critical analysis was then carried out with the previous parameters which were supposed to be responsible for rupture. The second part is about the built of a better numerical model. This goal led us to make a synthesis of different countries formulas used to estimate the subsidence parameters such as horizontal strains.
