چکیده

طی سال­های اخیر بالا آمدن تراز آب زیرسطحی در کلان­شهرها چالش­های متعددی پیرامون سامانه­های آب و فاضلاب شهری با اثرات تخریبی چندگانه ایجاد نموده است. این پژوهش با هدف شناسائی و وزن­دهی مخاطرات بالا آمدگی آب زیرسطحی کرمان بر سامانه­های آبفا با رویکرد مبتنی بر تحلیل سلسله مراتبی صورت گرفته است. بدین منظور براساس تحلیل وضعیت تراز آب زیرسطحی شهرکرمان و با بررسی آیین نامه­ها، دستورالعمل­ها، منابع موجود و نظرات خبرگان شاخص­های بیان­گر چالش­های پیش رو در 4 سطح و 18 آسیباستنتاج گردیده است. اولویت­بندی ارجحیت آسیب­ها براساس ماتریس مقایسه زوجی فردی و میانگین­گیری هندسی وزن­هابرای تبدیل به ماتریس مقایسه گروهی صورت گرفته و پس از تائید نرخ ناسازگاری سطوح آسیب و زیرمؤلفه­های آن­ها (I<0.1) تحلیل وزن­های نسبی و رتبه­بندی اولویت­ها با تحلیل سلسله مراتبی صورت گرفت. طبق نتایج آسیب­های بهداشتی - زیست محیطی با وزن 482/0، فنی-عملکردی با وزن 265/0، سازه­ای فیزیکی با وزن 145/0 و هزینه­ای اقتصادی با وزن 108/0 رتبه­بندی گردید. زیرمؤلفه­های تغییرمکان: نشست، ترک-خوردگی، تغییر شیب،جدایی اتصالات، خرابی آب­بندها با وزن نسبی 1/23 درصد، تغییر در کمیت و کیفیت آب و فاضلاب: نفوذ آب زیرزمینی به داخل شبکه و برعکس با وزن نسبی 3/38 درصد، نشت آلاینده ها از داخل شبکه آبفا به آب زیرزمینی و برعکس با وزن نسبی 6/30 درصد،  افزایشهزینه­هایتصفیهاولیهونهایی با وزن نسبی 1/32 درصد، به­عنوان بالاترین مخاطرات استنتاج گردید. تحلیل حساسیت مخاطرات نسبت به هرکدام از مؤلفه­ها نیز انجام شد.

چکیده [English]

With urban developments and the aging of urban water distribution pipes their demand  for repair and maintenance is rapidly grown. There are several factors that affect the performance and leakage in water and wastewater distribution networks (Ameyaw and Chan, 2016). By increasing the water leakage from pipes and wastewater depletion from houses to the injection wells, water level under the city ground is rising and saturation condition will be created near the underground infrastructures.
In recent years, local uplifting of subsurface water level in metropolises created different challenges over water and wastewater systems with multiple damage effects (Baah et al., 2015;Qiu et al., 2016).İn recent two decades, the rising of groundwater table in Kerman city have caused several challanges over the water and wasetwaer infrustructures. İn the ancint zone of the Kerman city, water level come up to 3 meter under the groundsurface and is interacted with several underground structures and basment flooding. The rising water table have several destructive  effects over the urban infrastructures. The main purpose of the present study is to investigate the effects of rising subsurface water level  in Kerman city by using an AHP based damage prioritization to depict the relative importance or urgency of a damages of water level rising over infrastructures.
