Abstract

The temple of Hatshepsut is considered as a most interesting ancient architectural monument and its stability is of real concern to human civilization. The temple is completely incised into the rock mass of Gebel Gurnah which is composed of Esna shale overlain by highly fracture Thebes limestone. Recently, two rock falls have occurred. A geotechnical characterization of the site around the temple was carried out. The present work aims to evaluate the probability of further limited circular failures in the Esna shale. This evaluation is achieved by using a near circular failure model based on the behaviour of intact rock, in conjunction with the CSIR rock mass classification system which gives the reduced mechanical properties due to the increase in discontinuity sets and weathering of the rock mass of the mountain around the temple.

Evaluation du risque de glissement d’un massif rocheux dans la vallée D’el-Deir El-Bahary, Louqsor, Egypte

Résumé

Le temple de Hatshepsout est consiéré comme étant un monument architectural ancien très interessant et dont la conservation est essentielle. Le temple est complètement taillé dans la masse rocheuse du Djebel Gurnah qui est constitué des schistes d’Esna surmonté du calcaire très fracturé de Thèbes. Deux écroulements rocheux se sont produits récemment, et une étude géotechnique du site entourant le temple a été réalisée. L’article présente les études qui ont cherché à prévoir de futures ruptures circulaires limittées dans les schistes d’Esna.

Cette estimation a été réalisée en utilisant un modèle de fracture quasi circulaire fondé sur le comportement de la roche intacte à partir du système de classification CSIR des massifs rocheux, qui donne la réduction des propriétés mécaniques due à l’augmentation des plans de discontinuité et à l’altération du massif rocheux qui entoure le temple.
