Description: Das Projekt "A scientific base towards the prediction of dissolution void geometry in limestone and dolostone" wird vom Umweltbundesamt gefördert und von Ecole polytechnique fédérale de Lausanne (EPFL), Faculté de l'environnement naturel, architectural et construit (ENAC), Institut des infrastructures, des ressources et de l'environnement (ICARE), Laboratoire de géologie de l'ingenieur et de l'environnement (GEOLEP) durchgeführt. The research task of the project is to provide a scientific base towards the prediction of karst dissolution void geometry in limestone and dolostone. Although belonging to academic research, results from this project will be applied to solve problems in tunnel engineering.Dissolution void distribution is not random, but defined by parameters controlling the 'speleogenesis', in other words the development of karst conduit networks. Some authors mentioned the existence of favourable horizons, which are called 'inception horizons'. The present project aims at:- evidencing the existence, of inception horizons in a large set of known karst systems, - demonstrating statistically their significance, - linking quantitatively their relation to some observable parameters, - evaluating the link between observable parameters and conduit characteristics.For this purpose research will focus on the study of the geometry of the longest cave systems in the World (more than 1500 km of conduits will be available for this analysis). The two largest systems located in Switzerland (190 km and 150 km respectively) will serve as principal examples.
