تحلیل وضعیت رها‌‌سازی نخاله‌های ساختمانی درحاشیه راه‌‌ها مطالعه موردی: کلانشهر کرج

اگر چه ضایعات ساختمانی بخشی جداناپذیر از پسماندهای شهری است، اما به دلیل تفاوت‌هایی که میان این ضایعات و پسماند‌ها و مسائل محیط زیستی دیده می‌شود باید اولویتهای مناسبی برای بهره‌وری و کسب منابع بهینه تعریف شود. هدف پژوهش حاضر را بررسی وضعیت رها‌‌سازی نخاله‌های ساختمانی درحاشیه راه‌ها، با بهره‌برداری از روش ترکیبی تحلیل شبکه‌ در تصمیم‌‌‌‌‌گیری چندمعیاره و محاسبات منطق فازی در محیط برنامه‌نویسی matlab است برای مدیریت نخاله‌های ساختمانی کلانشهر کرج، از تکنیک تصمیم‌گیری چندمعیاره و محاسبات منطق فازی در نرم‌‌افزارهای spss، expert choice و matlab استفاده شده است. حجم نمونه آماری پژوهش حاضر را، استادان دانشگاهی صاحب نظر در حوزه موردبررسی و متخصصان مدیریت پسماند و gis شاغل در سازمان شهرداری کرج و یا سمت‌‌های مشابه، تشکیل داده‌اند، در مجموع تعداد 30 پرسشنامه، با بهره‌برداری از تکنیک نمونه‌‌‌‌‌‌گیری غیر احتمالی هدفمند، در دی‌ماه 1399 جمع‌آوری شدند. یافته های پژوهش دلالت بر این دارند که مهم‌‌‌‌‌‌ترین معیار در خوشه عوامل محیط زیستی رها‌‌سازی نخاله‌های ساختمانی، آلودگی خاک در شهر است. همچنین مهم‌‌‌‌‌‌ترین معیار‌‌‌‌‌‌‌ها در خوشه مدیریت شهری ، سلامت و بهداشت می باشد. از طرفی دیگر، مهم‌‌‌‌‌‌ترین معیار در خوشه عوامل اقتصادی رها‌‌سازی نخاله‌های ساختمانی ، هزینه آموزش مدیریت نخاله‌های ساختمانی اولویت‌‌بندی شد، زیرا دارای بالا‌‌‌‌‌‌ترین رتبه فازی بر اساس محاسبات منطق فازی در محیط برنامه‌نویسی matlab، جهت مدیریت نخاله‌های ساختمانی کرج هستند. نتایج بصورت شفاف آسیب پذیری خاک و سلامت انسان را در برابر مدیریت غیر مسئولانه دورریزهای ساختمانی اثبات نمود . در نتیجه جایگاه این موارد و اولویتهای آنها باید در تنظیم مجدد فعالیت های ساخت وساز با هدف توسعه محیط زیستی ، اقتصادی ، اجتماعی و افزایش بهره‌وری فرآیند ساخت وساز مورد توجه قرار گیرد.

investigation of construction wastes release in roadside using ahp

investigation of construction wastes release in roadside using ahp introduction although construction waste is an integral part of municipal waste, due to the differences between this waste and waste and environmental issues, a suitable model should be designed for optimal productivity and acquisition of resources. the increasing volume of urban materials and rubbish, especially the rubbish from the destruction of their construction and worn out urban textures, has created many problems in large cities, as well as environmental problems that have arisen due to unprincipled and unprofessional disposal of these materials. has attracted these materials. research shows that the amount of this waste is equal to 10 to 15% of the total materials used in construction operations. this amount is much higher than what is estimated by the estimators. data and research method in iran and other developing countries, construction and construction waste is a major part of municipal waste, which in addition to high costs for its disposal, also has adverse consequences on the environment. the volume of this garbage is so much that now this issue has become a social and environmental problem not only in iran but also in developed countries due to the limitation of natural resources and preservation of national capital for future generations as well as environmental protection and it is necessary because with proper management and efficient planning and reducing the volume of construction waste, not only the waste of natural resources and national capital is prevented, but also additional and ancillary costs are reduced and it is economically beneficial. in this study, first, the effective criteria in selecting the burial site in the study area are determined. these criteria are reviewed and used by various standards, including standards related to the environmental protection organization, the ministry of interior and international standards, as well as by reviewing resources and studies on the process of locating landfills in the country and abroad and by examining the conditions of the region. the study and the influencing factors are compiled in the study area. the layers related to each criterion in the relevant table will be prepared, processed and converted from the relevant organizations. the method of this dissertation is applied modeling in terms of purpose, because on the one hand, the concepts and rules related to the field of knowledge are carefully analyzed, and on the other hand, the relationships between these concepts and rules are evaluated and determined by experts. in this study, there is a need to use the decision theory method to evaluate and investigate the status of construction waste disposal along roads to increase trust and confidence in decision making. the data analysis tools of this research are spss, expert choice and matlab for conducting the research. in the research process, after data collection, the next step involves data analysis. cronbach’s alpha coefficient was used to evaluate the reliability of the localization tools of the research components. in order to describe the data, the mean and standard deviation of the research data have been used. the four step process of multi criteria decision making process and fuzzy logic calculations to investigate the dumping of construction debris along roadsides is as follows: step 1 modeling causal relationships based on similarity to the ideal solution step 2 parallel comparisons and determining the weight of causal relationships based on the evaluation of decision options between the criteria for assessing the status of construction debris on the sidewalks, step 3 prioritize based on causal relationships based on evaluation of decision options step 4 fuzzy prioritization and final analysis investigation of construction waste disposal status result and discussion the most important results of the study of
