بررسی عوامل مؤثر در پالایش سطوح سنگی محوطه‌ی پاسارگاد با نگاه ویژه به هوازدگی فیزیکی و نقش آن در فرسایش

Abstract: Basically the monitoring means being aware of system’s condition or conservation of it and is one of the main parts of preventive conservation. Collecting and analyzing the data and information frequently, is a way to prevent damages that probably may occur in historical heritage that cause long time conservation fulfill by lower cost. The goal of this project is monitoring of Psargad heritage by noticing the main damage of the site that gathered by some librarian and case studies. In this way, description of Pasargad is done by concerning the physical weathering with studying the aspects of architectural, meteorological and pathology of stones. Then these damages were categorized by frequency & intensity. Also a complete study performed about monitoring and related aspects of it and the historical background, goal and necessities of it were also noticed. Some universal examples of monitoring in historical sites were introduced for knowing the equipment and methods of monitoring. Beside, this study design a system of evaluating the stone’s resistance that concluded by structural deformation (a kind of weathering that cause of effecting on freezing and atmospheric pollution that contains sulfuric aside compounds). Evaluating the possibility of using this system on the stones of historical site is another part of this study. Through these studies, the proposal monitoring design is presented for the stones of historical sites (case study: Bar-e Aam Palace). This design is performed by concerning of the condition and deformation monitoring and also effective factors in monitoring process of stone surfaces in this site.
