چکیده
مسئله تامین امنیت در بازارها، یکی از مهمترین عوامل در توسعه و رونق اقتصادی این اماکن شهری است. در همین ارتباط، میزان و کیفیت نفوذپذیری به این فضاها، عاملی تاثیرگذار بر این مهم می باشد. لذا پژوهش حاضر ضمن تحلیل کیفیت نفوذپذیری لبه های خارجی چند نمونه تیمچه به عنوان بخشی از فضای بازار، به بررسی مسئله تامین امنیت در این گونه از فضاها می پردازد. بر این اساس پس از تدوین چارچوب نظری تحقیق، سه پارامتر " خوانایی"، "کنترل و دسترسی بصری" و "یکپارچگی فضایی" به عنوان عوامل موثر بر امنیت فضایی معرفی گردید و با استفاده از تکنیک نحو فضا و در محیط نرم افزار Depthmap، به بررسی مسئله امنیت در نمونه های مورد نظر پرداخته شد. نمونه های موردی شامل هفت الگوی تیمچه با کیفیت نفوذپذیری متفاوت در لبه آنها می باشند. نتایج تحقیق نشان داد که تیمچه ی نفوذ ناپذیر از نظر شاخص خوانایی در سطح مطلوبی قرار دارد و به واسطه داشتن تنها یک ورودی، امکان کنترل ورود و خروج افراد را فراهم می آورد. این در حالی است که تیمچه ی چهار جهت نفوذپذیر، از منظر شاخص های کنترل و یکپارچگی فضایی در سطح بالاتری نسبت سایر به سایر تیمچه ها قرار دارد که این موضوع در تامین امنیت این گونه از تیمچه ها تاثیر بسزایی دارد.Check the quality of the security permeability edge of space (Case study: spatial analysis Timcheh structure in traditional Bazar)
In the historical form of the cities of Iran, the Bazzar is considered as an integral part of the city's structure which has formed the core and the main axis of the city and has guided the bones and development of the city. On the other hand, due to the economic role of the Bazzar in the city, the issue of security has been of particular importance. Therefore, it seems that the builders of this kind of buildings have special attention to their physical aspects in order to achieve this goal. For example, the establishment of Qaisarra as a space for the supply of valuable goods in the central Bazzar segment could be a effect in securing these usages. In this regard, it seems that the qualities of the edges of the Bazzar can also have a significant effect on this. Accordingly, the present study by investigates and analyzes various edges in the area around the Bazzar, examines the level of security in these spaces. On the other hand, Timcheh’s space was selected as a case study from among the various spaces available on the Bazzar. Therefore, the present study, while analyzing the permeability quality of the outer edges of several Timches, as part of the Bazzar space, addresses the issue of security in this type of space. In this research, space syntax technique has been used to analyze the configuration of the space of the towns. However, it is necessary to note that this technique is generally used to analyze the spatial structure of environments that consist of several small spaces. While the Timches in their physical structure are composed of spaces such as store, resting place, cellar, courtyards, corridors, entrances, Hashti, and so on. This justifies the application of this technique in the analysis of this kind of construction. After reviewing the literature, three indicators including “readablity”, “visual control and access”, and “space integration” were considered as theoretical framework of the research and tools like “Step depth”, “Integration”, “Connectivity”, “Physical accessibility(Metric depth)”, “Isovist area”, and “Isovist perimeter” were used to analyze them in the Depthmap software environment. The results of the study showed that the impermeable Timcheh in terms of readability index is in a desirable level, and due to having only one input, it is possible to control the entrance and exit of individuals. However, the four-directional permeable Timcheh in term of control and spatial integration indicator are at a higher level than the other Timches this has a significant impact on the security of these Timches. Also, the edge properties of the input (s) are more important in providing space security. Because it determines the amount of accumulated load to space and thus the permeability to space. The location of the Timches is one of the other things that have a significant impact on their security and their creation of crime scenes. Moreover, the presence of concave geometries in the space structure leads to inadequate visual visibility and the possibility of a massive increase in space.
