摘　　要：Rockfall risk is often mitigated and managed by employing defensive structures to catch falling blocks(i.e.,passive works).Due to the widely spread nature of rockfall,the presence of such defensive structures is a common sight,especially in mountain areas.The most common passive defensive structures are rockfall flexible barriers,due to their significant flexibility and cost-effectiveness.The protective performance of said structures,though,can be severely reduced by prolonged exposure to weathering agents,vegetation growth,and rockfall impacts:these issues must be addressed by performing maintenance.With a view to optimizing the maintenance procedure,the need arises for a tool capable of providing useful information regarding the condition of existing rockfall barriers,in the simplest yet most complete and comprehensive way possible.The present work provides such a tool,alongside the required instruments for it to function properly.Basically,it consists of a survey spreadsheet to be used to collect raw data based on visual inspection of the barriers,coupled with the methodology to score their conditions and to produce a database with which to manage and plan their maintenance.An application to a suitable case study in the Central Italian Alps,featuring a number of barriers in different conditions,is then presented,and its results are discussed.
