Apport de l'archeologie experimentale a la comprehension du creusement des tranchees d'implantation des allees couvertes de la fin du Neolithique.En marge des fouilles au champ megalithiquede Weris (Belgique)

摘要

The digging of the foundation pits of the semi-buried allees couvertesfrom the Late/Final Neolithic were remarkable achievements whose techni-cal and social requirements had not previously been experimented. Thispaper describes experiments conducted to test several aspects of this 'mega-lithic engineering'. A number of practical and potentially significant ques-tions were examined, among them the efficiency of the different sets of toolspossibly used for the operation, how the material dug out was disposed ofhow many people were involved and, finally, the maximum length of timeneeded for such endeavours.
