چکیده

تاب‌آوری زیرساخت‌های حیاتی در برابر حوادث، قبل، حین و پس از بحران برای پاسخ و ترمیم حادثه ضروری است. جنبه‌های بحرانی تاب‌آوری مانند برنامه‌ریزی برای شرایط خطرناک و درگیر شدن با محاسبه وابستگی درونی با سایر زیرساخت‌ها باید درک شود تا مدیران بتوانند تاب‌آوری سیستم را ارتقاء دهند. سامانه انتقال فاضلاب به‌عنوان یکی از زیرساخت‌های حیاتی شهری محسوب می‌گردد. عملکرد بدون وقفه­ی سامانه فاضلاب برای کلان‌شهر تهران با توجه به حجم زیاد فاضلاب موجود از اهمیت بسزایی برخوردار است، این عملکرد در مواجه با حوادث غیرمترقبه تابع میزان تاب‌آوری آن سامانه است. در همین راستا هدف پژوهش حاضر، ارزیابی تاب‌آوری زیرساخت خط انتقال فاضلاب کلان‌شهر تهران به تصفیه‌خانه فیروز بهرام است. از نظر روش­شناسی پژوهش حاضر از نوع کاربردی بوده و روش گردآوری اطلاعات با استفاده از منابع کتابخانه‌ای و روش مصاحبه باز صورت پذیرفته است. به همین منظور با توجه به انواع تهدیدات خط انتقال فاضلاب، فاکتورهای مؤثر در تاب‌آوری آن از متون ادبیات موضوع ارائه می‌شود و پس‌ازآن با کمک روش ارزیابی تاب‌آوری زیرساخت (IRAM)، بومی‌سازی آن برای خط انتقال فاضلاب به تصفیه‌خانه فیروز بهرام انجام می‌گردد. نتایج به‌دست‌آمده نشان می‌دهد که وضع موجود تاب‌آوری لازم را نداشته و حجم عظیمی از فاضلاب بر اساس سناریوها به محیط شهری و دیگر زیرساخت‌ها وارد و آسیب می‌رساند، به همین منظور در انتها راهکار «طرح اجرای بای پس فاضلاب به رودخانه کن» به‌منظور ارتقای سطح تاب‌آوری پیشنهاد گردید که بر اساس تحلیل‌های انجام‌شده بعد از اعمال راهکار، سطح ارتقاء تاب‌آوری (اختلاف RDR اولیه و ثانویه) افزایش پیدا می‌نماید.

چکیده [English]

Resilience is defined to enhance the ability of the community, planning and readiness to achieve and improve more success in dealing with adverse effects of catastrophes providing the view of repairing and improving the injured community. Resilience of critical infrastructure in the face of disasters, before, during and after a crisis is essential for proper response and recovery. Critical aspects of resilience, such as planning for hazardous situations and engaging with the calculation of infrastructures' interdependence must be understood so that managers can enhance system resilience. Wastewater transmission and treatment system is considered as one of the important urban infrastructures. Due to the large volume of available wastewater, uninterrupted operation of the sewerage system for the metropolis of Tehran is really important. This performance in the face of unexpected events is a function of its system resilience. The purpose of the current study is to evaluate the resilience of the wastewater-transmission tunnel infrastructure of Tehran metropolitan to the treatment plant of Firooz Bahram. Also, methods of collecting data are based on library resources and face-to-face interview. Thus, considering the threats of the assets of the sewage transfer tunnel, the effective factors in its resilience are presented from the its literature. Then, with the help of Infrastructure Resilience Assessment Method (IRAM), its localization for the sewage-transmission line to Firooz Bahram treatment plant will be done. The results indicate that the current situation does not have the necessary resilience and a large volume of wastewater enters and damages the urban environment and other infrastructure based on scenarios (resilience costs). At the end to address the issue, the solution "Implementation plan of sewage bypass to Kan River" will be proposed and evaluated to improve the level of resilience. Evaluation of the results for implementation of the improve - resilience strategy (primary and secondary RDR difference) approves positive effect.
