Contribution à l'analyse systémique, à la modélisation de la production et du déplacement des poussières lors de la démolition par foudroyage

Abstract : The demolition of buildings caving is a technique which has become classic. The demolition generates nuisance that must be taken into account, under penalty of rendering this type of demolition. The main nuisance generated by the caving are: - The projections generated by the explosion and the disintegration of the building; - The pressure wave generated by the explosive; - The ground vibration induced by the collapse of the building; - The creation and spread of a cloud of dust. The first two points are controlled. With regard to vibration, no method exists to limit them. Only the ditches can provide access to a shadow effect vis-à-vis some buildings. Nuisances generated by dust and ways to limit them begin to be a common question. As part of the destruction of classified installations for environmental protection, this issue becomes critical because the cloud can move harmful particles. Currently, no information on the mechanisms of production or on the mechanisms of spread of dust has been developed. This thesis proposes a measurement protocol for the study of the characteristics of cloud particles. It prensetes the first information on the production and propagation of the particles. And finally presents the first numerical simulation of the phenomenon.
