The Influence of the Passive Earth Pressure and other Factors on the Stability of the Underground Masonry Vaults of the Paris Metro

Abstract

The paper introduces the main concepts and criteria presented in the Guidelines on the Analysis, Conservation and Structural Restoration elaborated by the ICOMOS/ISCARSAH committee. The guidelines have been developed with the aim to provide guidance to experts and practitioners working in the study and conservation of structures or the architectural heritage. The guidelines are based on the ICOMOS Charter on the Principles for he Analysis, Conservation and Structural Restoration of Architectural Heritage elaborated by ISCARSAH and adopted by ICOMOS in 2003. The guidelines are intended to assist the multidisciplinary teams involved in the management of historical structures across all the stages of the study and operation, including the investigation and documentation works, the structural verification and the selection and design of appropriate minimum interventions.
