Abstract

Despite the importance of mudrock in engineering projects in comparison with other sedimentary rocks there is little information available on the mechanical properties of these materials Probably one of the main reasons for this lack of data is that on a practical basis mudrocks can easily be disturbed by normal drilling techniques and are frequently difficult to sample store characterize and test A number of tests were carried out and a considerable amount of data collected from the literature to investigate the mechanical properties of different types of mudrocks Reasonably good correlations were found between some index parameters and mechanical properties and various regression equations are proposed for predicting mechanical properties In view of the closeness of these correlations and the fact that the index parameters of mudrocks are relatively simple to determine the correlations provide an indirect but very convenient means of estimating the mechanical properties It is suggested that in some circumstances their use may reduce testing requirementsMalgré limportance des argilites dans les projets dingénierie peu dinformation est disponible sur les propriétés mécaniques de ce type de roche par comparaison avec dautres roches sédimentaires Probablement lune des raisons principales de ce manque de données réside dans la difficulté à travailler avec des argilites En effet ce type de roche est difficile à échantillonner conserver caractériser et tester Ce matériau peut facilement être remanié par la foration léchantillonnage et la préparation des épreuves dessai De nombreux tests ont été réalisés et un grand nombre de données rassemblées à partir de la bibliographie afin détudier les propriétés mécaniques de différents types dargilites Le but principal de cette étude est dexpliquer les relations entre propriétés physiques et mécaniques en particulier les corrélations entre indices géotechniques et propriétés mécaniques Dassez bonnes corrélations existent entre quelques indices géotechniques et propriétés mécaniques et diverses équations de régression sont proposées pour prédire des propriétés mécaniques Du fait de la précision de ces corrélations et parce quil est facile de déterminer des indices géotechniques dun échantillon dargilite ces corrélations fournissent un moyen indirect mais correct pour estimer des propriétés mécaniques Ainsi ces équations de régression peuvent permettre de réduire le nombre dessais mécaniques nécessaires à la caractérisation du matériau
